Frequently Asked Questions

Q: Is the BISCO BF-1000 foam compatible with acrylic or polycarbonate?

A: Yes, the BF-1000 foam is compatible with most plastics including acrylic and polycarbonate. It will not cause crazing or cracking issues.

Q: What are some alternatives to the BF-1000 foam?

A: Some alternatives include Poron urethane foams, lower density silicone sponge rubber, EVA foam, and various felt or fabric materials. However, none offer the same softness and temperature resistance as the BF-1000.

Q: Does the foam require adhesive to mount it?

A: In many cases no adhesive is required as the foam can be held in place with pressure sensitive adhesion. For permanent bonding, silicone RTVs or contact adhesives work well.

Q: Can the foam withstand outdoor exposure?

A: Yes, the BF-1000 foam has excellent UV and oxidation resistance allowing it to withstand long-term outdoor exposure.

Q: Is the foam available with adhesive backing?

A: Yes, many suppliers offer the BF-1000 with pressure sensitive acrylic or silicone adhesive backing for ease of application. The adhesive increases the cost slightly.
