Product Description

 

Product Description

 

ULEAT00-380 is a highly effective hydrophilic fumed silica produced through the combustion and hydrolysis of chlorosilane in a hydrogen-oxygen flame at temperatures exceeding 1000°C.
This innovative material is widely used in industries such as liquid silicone rubber (LSR), adhesives, coatings, inks, catalyst carriers, food, and plastics.
Thanks to its remarkable high specific surface area and ultra-fine particle size, it delivers superior transparency, exceptional thickening, reinforcement, and rheological properties.
 

Detailed Product Description

1. Key Features:

Excellent Transparency - Ideal for applications requiring clarity.
Superior Thickening & Reinforcement - Enhances viscosity and mechanical strength.
Stable Rheological Effects - Ensures smooth application in coatings and adhesives.
Wide Industrial Applications - Suitable for LSR, plastics, food-grade products, and more.
High Purity & Consistency - Manufactured under strict quality control for reliable performance.

 

2. Applications

 

Liquid Silicone Rubber (LSR)
ULEAT00-380 is a popular additive in LSR formulations, improving mechanical strength and flow properties while maintaining excellent transparency.

Adhesives & Sealants
This powerful fumed silica acts as a thickening and anti-settling agent, ensuring stable viscosity and long-lasting adhesion.

Coatings & Inks
Due to its small particle size, it enhances scratch resistance, durability, and printability in coatings and inks.

Food Industries
As a food-grade additive, it improves texture and stability in powdered food products.

Plastics & Composites
It reinforces plastic matrices, increasing tensile strength and heat resistance.
