Product Description

Product Description

Product Name:Vinyl Ester Resin HS-4483B

1. Brief Introduction:HS-4483B is a meticulously engineered vinyl ester resin, purpose-built for high-speed pultrusion molding. Featuring moderate viscosity and high reactivity, it significantly accelerates pultrusion line speeds. This advanced resin not only enhances product surface gloss but also minimizes shrinkage and internal microphase cracking. Pultrusion products crafted using HS-4483B boast exceptional corrosion resistance, mechanical integrity, and electrical properties. HS-4483B is the optimal choice for manufacturing fiber optic cable strengthening cores.
Pultrusion products produced by HS-4483B possess outstanding corrosion resistance, superior mechanical properties, and excellent electrical characteristics. HS-4483B is particularly ideal for the production of fiber optic cable strengthening cores.

4. Storage:
1) Store in a dry place away from heat sources like direct sunlight or steam pipes, at temperatures below 25ºC.
2) Ensure containers are sealed to prevent moisture absorption and monomer loss. Extended storage beyond recommended conditions may affect the liquid resin's properties such as viscosity and gel time.
3) Transportation should comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations'. Due to the presence of styrene monomer, this product is classified as hazardous and flammable.
