SURFACE MODIFICATION

compounder


Our additives for the surface modification of compounds include antiscratch additives, haptic enhancers, slip agents for COF reduction and anti-squeak, stain preventers, antifogging and antistatic additives.

Evonik offers antiscratch additives for polyolefins like PP/talc compounds for automotive interior as well as for technical polymers like PA, PMMA or PC/ABS. The antiscratch effect is durable and long lasting and it is not accompanied by undesired side effects like odor, fogging or an increase of the surface tackiness.

Our haptic enhancers soften the touch of automotive interiors, appliances or fibers.

Our slip agents reduce the coefficient of friction (COF). Furthermore, they enable anti-squeak properties. Less abrasion of moving plastics parts or sealants for glazing is obtained.

Our stain preventers help to improve the stain resistance of appliances.

In food packaging fog formation leads to unfavorable appearance and may cause food spoilage. Our cling & antifogging additive TEGO® STS acts as surface active or wetting agent and prevents the formation of discrete water droplets.

The antistatic additive TEGIN® 90 provides resistivity control. As the additive migrates to the surface at different speeds, the effect develops at different rates, depending on the polymer type. 

ADDITIVES FOR SURFACE MODIFICATION:


  • ACCUREL® SF 1710

    ACCUREL® SF 1710 gives molded parts a smoother surface appearance.

  • TEGOMER® AntiScratch 100

    TEGOMER® Antiscratch 100 significantly increases the scratch resistance of plastic compounds (pp/talc) used for car interior applications like door panels or center console trims. In contrast to standard additives TEGOMER® AntiScratch 100 guarantees a durable and long lasting effect. Moreover, TEGOMER® AntiScratch 100 is a non-migrating additive which does not cause fogging, it has no influence on the haptics of the surface and the additive is absolutely odorless.

  • TEGOMER® AntiScratch L

    TEGOMER AntiScratch L is a liquid organo modified siloxane that iincreases the scratch resistance of plastic compounds. Tegomer AntiScratch L can be used in filled and unfilled plastic compounds and is useful for polyolefines as well as for engineering plastics.

  • TEGOMER® H-Si 6441 P

    TEGOMER® H-Si 6441 P is a polyester modified siloxane which is delivered in pellet form with excellent compatibility in thermoplastic and duroplastic resins.

  • TEGOMER® M-Si 2650

    TEGOMER® M-Si 2650 is used as an additive for thermoplastic elastomers, polyesters, polystyrene and technical compounds.

  • TEGOPREN® 6846

    TEGOPREN® 6846 is an organic modified siloxane based wax, especially designed to improve the processing and final performance of polyolefin.
