About This Product

■Features

・Can be mixed with colored rubber and transparent rubber ・Improves rubber elongation and tensile strength ・Low rolling resistance ・Excellent bending fatigue resistance

■Silica for rubber reinforcing filler

Rubber reinforcing fillers are compounding agents that combine with rubber to improve the strength (reinforcing properties) of rubber. "Carbon black (C/B)" is known as a typical rubber reinforcing filler and is used in rubber products that require high strength. Like carbon black, silica also improves the strength of rubber, so it is commonly called "white carbon." Application examples and recommended grades

■Industrial rubber reinforcing filler

Rubber parts are used in automobiles (excluding tires), buildings, electrical parts, etc., tailored to each purpose. Depending on the use of rubber parts, various functions are required, such as reinforcing properties, compression set, and dynamic magnification, so it is necessary to select a silica grade that matches each function. We have a wide variety of grades available to meet such diverse needs.

■Reinforcing filler for silicone rubber

Silicone rubber is a highly transparent rubber with excellent heat resistance, cold resistance, and weather resistance, so it is used in rubber parts in a wide range of fields. Our reinforcing filler grade for silicone rubber can improve reinforcement properties and flex fatigue resistance without compromising transparency.

■Rubber reinforcing filler for tires

Silica is often used in fuel-efficient tires to reduce the tire's rolling resistance. Due to increasing awareness of environmental issues, fuel-efficient tires are becoming widely recognized, and sales of tires with higher fuel-efficiency performance are increasing. In order to meet these needs, we are also focusing on developing a grade exclusively for fuel-efficient tires, and in recent years we have significantly improved the wear resistance performance (long life performance), which has been a weak point of silica-containing tires. We have succeeded in developing silica.

■What is rebound resilience (item)

Expresses the ratio of applied force to rebound force. For example, if you drop a weight on rubber that has a rebound modulus of 100%, it will bounce back to its original position, but if you drop a weight on rubber that has a rebound modulus of 0%, it will stop in place without bouncing back at all.
