Silicone toughening agent 135
KH-135 silicone toughening agent
Overview:
This product is a pure silicon system silicone toughening agent, 100% effective content, does not contain any carrier and other compounds, used in PC, ABS and its alloy compounds. It has excellent weather resistance, low temperature resistance, impact modifier and high cost performance.
product description:
Appearance: colorless transparent viscous liquid,
Molecular structure; silicone polymer containing reactive groups
Product Features:
◆ Pure silicone system provides PC, ABS and alloy impact and low temperature impact modifiers;
◆The silicone structure provides excellent weatherability and cold resistance to plastics; and excellent anti-yellowing;
◆ can improve the processing fluidity, reduce the fat melting, and improve the surface finish of the product;
◆ Make plastic coloring easier: This product can adhere to toner, make color even, and reduce the amount of dispersant or diffusion oil.
◆ This product is a transparent material, free of impurities and sediments, and will not affect the transparency and color of the plastic. And easy to add, as long as the particles are evenly stirred, and can help disperse the toner, can reduce the use of diffusion oil.
◆The minimum addition amount (0.3-0.5%) is recommended to add one ton plus 4KG, which has obvious impact resistance and helps reduce cost. It can give the material excellent weather resistance and low temperature resistance.
