Purchasing Guide

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

  • For procurement requirements that require the use of silicone, it is recommended to clarify product specifications such as hardness (Shore A), tensile strength, and temperature resistance range (-60 ℃ to 250 ℃). The parameter differences between industrial grade and food grade silicone need to be distinguished and verified.
  • Silicone is widely used in medical devices, kitchenware sealing, and electronic sealing. When purchasing, corresponding tear resistance or biocompatibility characteristics should be selected according to the actual use.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure supply stability.
  • Special models such as high transparency or conductive silicone need to be validated in conjunction with production processes. It is recommended to evaluate their resilience and durability through sample testing to ensure they meet project requirements.
