애플리케이션

Additive to unsaturated polyesters, epoxides and other polymers to impart the unique properties of UHMWPE. Used in industrial parts, coatings and wear surfaces at 10-40 wt. %.

특징 및 장점

Polar surface groups assist chemical and physical bonding to matrix material. Contributes superior abrasion resistance, reduced coefficient of friction, enhanced tear strength and improved moisture resistance. Easier to process in particle form than molten UHMWPE.

물리적 형태

Particle surface is modified to contain acid and hydroxy groups.
