German High Temperature Reversion Resistant Silicone
Solid Silicone Sheet
High Temperature Reversion Resistant Silicone is a specialized form of silicone rubber designed to withstand extreme temperatures without undergoing significant chemical or physical changes.
The key advantage of High Temperature Reversion Resistant Silicone is its ability to maintain physical properties and resist chemical breakdown at temperatures where normal silicone would degrade. This makes it an invaluable material in any situation where durability and performance under extreme heat are required. Applications include press pads for flexible and printed circuit boards, release sheets in bonding processes, and high-strength gasketing.

More Information
ASTM D412
- ASTM D412 is a standard that outlines methods for testing the tensile properties of vulcanized rubber and thermoplastic elastomers.
- It measures properties like tensile strength, elongation, stress-strain characteristics, and modulus of these materials.
- The test involves stretching a rubber or elastomer specimen at a constant rate until it breaks, to assess its strength and elasticity.
- This test is crucial in evaluating materials for products that require high elasticity and strength, such as tires, hoses, belts, and various rubber components used in mechanical and automotive industries.
ASTM D624
- ASTM D624 is a standard test method for tear strength of conventional vulcanized rubber and thermoplastic elastomers.
- It is used to measure the resistance of these materials to tearing, which is crucial for determining their suitability in various applications.
- The test involves cutting a sample into a specific shape and applying tension until it tears, measuring the force required for initiation and propagation of the tear.
- This test is vital in industries where durability and tear resistance are essential, such as in automotive parts, seals, gaskets, and consumer goods.
ASTM D2240
- ASTM D2240 is a standard test method for determining the hardness of rubber materials and plastics using a durometer.
- This test measures the depth of indentation in the material created by a specified force from a standardized indenter, providing a hardness value.
- The hardness value obtained is critical for assessing the material’s suitability in various applications, including automotive, aerospace, consumer goods, and medical devices.
- It’s widely used for different types of rubber and plastic materials, offering a quick and reliable way to assess material properties for quality control and product development.
