Product Description
HB silicone sponge refers to a type of silicone sponge that meets the UL 94 HB flammability rating. This rating indicates a material's resistance to burning, with HB representing a moderate level of flame resistance, meaning the material will self-extinguish within a specified time after ignition,
UL94 is a flammability rating system used for plastics in electrical devices and appliances, developed by Underwriters Laboratories (UL). It categorizes materials based on their burning rate, self-extinguishing behavior, and other factors related to flame spread.
HB level:
Slow burning, often with a burning rate less than 76 mm/min for thinner specimens or stopping before reaching a certain length.

Usage and storage
When using double-sided tape, the surface to be bonded must be cleaned to ensure it is free from impurities such as oil, water, dust, and dirt. It is recommended to clean the surface with isopropyl alcohol (IPA)
When stored unopened at or below room temperature (avoiding direct sunlight, not exceeding 35°C and 70% relative humidity), the product has a shelf life of 10 years from the date of production
