Superb Resistance and Non-Allergenic.

Synthetic polyisoprene is produced with a synthetic version of the same base polymer as natural rubber latex, then compounded to mirror the same properties. It is a safe alternative for those with latex allergies and counted on for a wide range of uses where latex-allergens are a concern, including the medical, food and beverage, and sports and recreation industries.

With the benefits of natural rubber latex still desired, synthetic polyisoprene compounds are a versatile, resilient, and natural latex-free alternative that are safe for use in a wide range of industries. Our customers count on our expertise to provide the right solutions for their industry and keep their deadlines on track—from the prototype to the testing phase for their synthetic polyisoprene products.

Alternative Compound for Dip-Molded Products.

At Kent Elastomer Products, we offer synthetic polyisoprene as an alternative compound for dip-molded products. Our compound K-440 has a base polymer the same as natural rubber but is polymerized in a reactor producing an artificial latex. K-440 is the best product available for medical applications and beyond that demand the properties of natural rubber latex without latex-allergen concerns.

K-440 is manufactured to meet the demands of the medical and surgical, dental, sports and leisure, and food and beverage industries and beyond. Compatible for medical devices, K-440 has been tested and passes USP XXII Biological Class VI Testing. This compound is also food grade compliant, meeting all recommended safety levels as specified by the United States FDA Code of Federal Regulations, Title 21.

Advantages of Synthetic Polyisoprene.

The most significant advantages of synthetic polyisoprene compared to natural rubber is the purity, consistency and homogeneity of the polymer structure. Synthetic polyisoprenes are non-allergenic and offer good processability and purity compared to natural rubber. They are also competitively priced thanks to the efficiencies that are gained in the consistency of their manufacturing process. Synthetic polyisoprenes are also durable and have high tensile strength, good adherence, and good resistance to abrasion, inorganic chemicals, weather and cold.

Synthetic polyisoprenes have better resistance to weather than natural rubber latex, although it does sacrifice some tensile strength, tear resistance and compression set. Applications of synthetic polyisoprenes are similar to natural rubber, including tubing, dip-molded products, sports equipment, medical equipment, protective gloves, conveyor lines, adhesives, sealants and more.
