Name: CVI PS-1 Toughener
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of CVI PS-1 Toughener

Enhances impact resistance and fracture toughness of epoxy and vinyl ester resins without compromising thermal stability.
Offers excellent compatibility with standard thermoset resin systems, enabling uniform dispersion and stable formulation.
Reduces microcracking under thermal cycling and mechanical stress, improving long-term durability of composite laminates.
Non-reactive modifier — requires no additional catalysts or cure adjustments during standard processing.
Low volatility and low odor, supporting safer handling and compliance with industrial hygiene guidelines.

Typical Applications Of CVI PS-1 Toughener

Aerospace structural composites requiring high damage tolerance and fatigue resistance.
Wind turbine blade matrices where interlaminar shear strength and delamination resistance are critical.
Marine hull and deck laminates exposed to cyclic loading and moisture ingress.
High-performance automotive under-hood components subjected to elevated temperature and vibration.
Electrical insulation systems in medium-voltage transformers and bushings.
