Intelimer Polymers® are semicrystalline graft copolymers that exhibit novel, valuable properties and benefits. The melting temperature of Intelimer Polymers can be tuned to a specific target temperature. Heating the polymer through this melting temperature produces a transition from a semicrystalline to an amorphous state. This transition can be used as a “temperature switch” to modulate properties such as viscosity, permeability, adhesion and specific volume. These “temperature switch” properties can be used to trigger or change product performance in ways that make Intelimer polymer based products and materials unique and differentiated.
Intelimer polymers can be designed to contain over 80% renewable naturally sourced materials and can be supplied in both bioerodible and biocompatible forms.

Intelimer Polymers® can be customized to abruptly change physical characteristics in response to an environmental trigger.
For instance, Intelimer Polymers can change from a non-adhesive state to a highly tacky, adhesive state; from an impermeable state to a highly permeable state; or from a solid state to a low viscosity fluid state. These transitions result from the architecture of the Intelimer polymer chain, which includes crystallizable side chains attached to the polymer backbone. The side chains switch between crystalline and amorphous morphologies as the defined temperature trigger point is crossed. Because these charges are a physical change in the polymers and not a chemical change the process is repeatedly reversible. Trigger points can be tuned over a wide range. Temperature triggers, for example, can be set from 0 to 105°C and pH triggers can be tuned to modify release at high or low pH.
SAMPLE APPLICATIONS: Membranes and coatings with thermally triggered permeability of gases and liquids; adhesives that are thermally triggered to transition from tacky to non-tacky; rheological control additives that are activated when they reach skin temperature; catalysts that are released at a specified temperature; coating that respond to temperature change by turning water permeation on or off and more.
Intelimer Polymers® simplify processing. Above their melting point, the polymers exhibit low viscosity fluid properties allowing them to be combined with other ingredients without requiring solvents and eliminating the need for energy-intensive high temperature mixing methods such as melt extrusion. Upon cooling the mixture below the melting point, crystallization occurs rapidly and the formulation assumes a solid form. Since the melting point can be adjusted over a wide temperature range, sensitive materials can be formulated without significant loss of function. The melting point itself is determined during the synthesis of the polymer and can be set to within 1°C over a wide range of temperatures within the range of 0-105 °C.
SAMPLE APPLICATIONS: Hot melt extrusion at lower temperatures, processing of a temperature sensitive active ingredients, and more.
Intelimer Polymers® are synthesized from long side-chain acrylic monomers that are derived primarily from natural renewable materials such as canola (rapeseed), coconut, and palm oils.
These materials are highly purified and designed to be manufactured economically through known synthetic processes. We polymerize these acrylic-monomer starting materials into many different side-chain crystalline polymers whose properties vary depending upon monomer composition and the synthesis process. Intelimer Polymers can be designed to incorporate up to 80% renewable materials and can be supplied in biocompatible and bioerodible forms. We synthesize the Intelimer Polymers through a variety of means including solution, emulsion and bulk polymerization (solvent free).
SAMPLE APPLICATIONS: Renewable materials are incorporated in all Landec Intelimer polymers.
Landec’s Intelimer Polymer® is used as an ingredient in over fifty personal care products – and this number continues to grow. Landec has an exclusive partnership with Air Products and Chemicals, Inc, which manufactures Intelimer personal care additives for use in sunscreens, color cosmetics, anti-aging creams, hair care, and acne prevention products.

The unique properties inherent in Intelimer Polymer technology have been applied to agricultural seed coatings and treatments. Landec’s coatings and formulations are used to regulate seed germination, protect seeds under adverse field conditions, deliver fungicides and insecticides with low dust off and good seed flow and provide sustained release of nutrients and pesticides.
SEED ENHANCEMENT COATINGS
Seed enhancement coatings improve the germination of crops such as corn and soybeans, protecting the seeds from adverse field conditions and environmental stress. Seed enhancements are used to promote good germination and improved seedling vigor resulting in a healthier crop and thus enhanced yield potential of high-value seeds.
- Intellicoat® Pollinator Plus®* seed coatings were developed to be used by seed companies to delay germination and enhance an optimal natural crossing of genes in the production of hybrid seeds. Pollinator Plus is widely used in hybrid corn seed production, with use in over a half million acres since 2000. Pollinator Plus works by delaying the germination of male inbred seeds to expand the pollen shed window to better match the silking duration of female plants. Seed producers benefit by eliminating the need for split plantings and flaming operations. Use of Pollinator Plus results in higher efficiency, safer operations, improved seed purity, and overall enhanced yield. In 2012 Landec licensed the global rights to Pollinator Plus to INCOTEC.
- Early Plant™ Corn seed coatings were developed to enable farmers to plant corn up to four weeks earlier than normal in the planting cycle. The seed coating controls permeability, using the temperature triggered properties of Intelimer Polymers. Below a pre-set temperature the coating restricts permeation of water protecting the seed from cold wet soils. When the soil temperature warms up above the pre-set temperature of the coating, water begins to permeate the coating and the seed absorbs water rapidly and germinates under ideal conditions resulting in good stand establishment.
- Relay Crop™ Soybean coatings were developed to allow farmers to harvest two crops in one field. Coated soybean seeds are planted in early spring into fall planted spring wheat. The coating delays the germination of soybeans by 20-30 days after planting, leaving time to establish a stand prior to wheat harvest. The delayed emergence of soybeans allows farmers to harvest their winter wheat crop first while the soybeans plants are small, still under ten inches, thus not impacting the soybean development. Farmers improve overall field yield and efficiency by harvesting two crops from one field. This method is superior to traditional double cropping where stand establishment of soybeans depends on available soil moisture at the time of planting.
SEED TREATMENT COATINGS
Seed Treatments are fast drying coatings that provide superior dust-off, improved handling (flowability) of seeds, and compatibility with a range of fungicides and insecticides. The CT-1000 coating is used for hybrid corn and the ST-1000 coating is used for soybeans.

Landec leverages the unique temperature triggered properties of Intelimer polymers to create adhesives that reversibly transition from a tacky adhesive to a non-tacky, non-adhesive state at a precise tunable temperature. Landec’s Warm-Off technology transitions from an adhesive to non-adhesive state when the temperature increases above a pre-set transition point, whereas Landec’s Cool-Off technology transitions from an adhesive state to a non-adhesive state when the temperature decreases below the pre-set transition point.
Landec has an exclusive partnership with Nitta Corporation for the sale and distribution of Intelimer Warm-Off and Cool-Off adhesive technologies within the electronics industry. Nitta Corporation sells Intelimer Tapes used during the manufacture of electronic components when adhesion and/or temporary positioning are critical to efficient high-quality processing. Below are two examples showing how Intelimer Tapes can be critical to the processing of electronic components:
Carrier and Protective Tape: Intelimer Tape is used as a carrier during conveyer operations. The workpiece adheres to the tape during processing, providing secure positioning and added strength and protection from soiling during high temperature and abrasive etching and other operations. The workpiece is easily removed from the tape when processing is complete and heat is removed.
Transfer Tape: Intelimer Tape is used during the transfer process by using two different Intelimer Tapes, each with different transition temperatures. A workpiece is adhered to Tape 1 during transfer at Temperature 1. When there is a change to Temperature 2, Tape 2 is lowered onto the workpiece. The workpiece then adheres to Tape 2 and is easily released from Tape 1 for subsequent processing and manufacture.
