Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of vulcanized silicone rubber, it is recommended to clarify key technical parameters such as hardness, tensile strength, and temperature resistance range based on application scenarios (such as seals, insulation materials, or medical devices) to ensure performance matching.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to balance procurement risks and efficiency.
  • Vulcanized silicone rubber used in high-temperature or chemically corrosive environments requires additional attention to its aging resistance and tear resistance to avoid equipment failure due to material failure.
  • There may be performance fluctuations in different batches of vulcanized silicone rubber. It is recommended to verify the stability of the supplier's products through small-scale trials before expanding the procurement scale.

Knowledge Base

Q

This article introduces the definition, preparation methods, characteristics, and application fields of vulcanized methyl silicone rubber, and analyzes its importance in industrial production.

Q

High temperature vulcanized silicone rubber refers to the process in which polydimethylsiloxane is transformed into an elastomer through high-temperature (110-170) vulcanization molding. It mainly uses high molecular weight polyethylene siloxane as raw rubber, mixed with reinforcing fillers, vulcanizing agents, etc., and vulcanized into elastomers under heating and pressure. The reinforcement of silicone rubber is mainly various types of white carbon black
