Is Butyl Rubber Flammable

Butyl rubber sometimes just called butyl is a synthetic rubber a copolymer of isobutylene with isoprene the abbreviation iir stands for isobutylene isoprene rubber.

Is butyl rubber flammable. The purpose of this write up is to aid polymer and rubber compounders who are seeking basic information on the flammability and burning behaviors of polymers. Generates flammable hydrogen with alkali metals and hydrides. If heated above the flash point they may burn or decompose to flammable hydrocarbons fire situations. Butyl rubber polymers are solid stable polymers that are not hazardous and highly impermeable to air and water relative to other rubber polymers.

Butyl rubber is produced by polymerization of about 98 of. Butyl lok emulsion non flam or solvent flammable adhesive primer be coated on the joint surface and allowed to dry a minimum of 10 minutes before application of joint sealant. Be careful though because they also are flammable until they cure shrink significantly and have a high percentage of volatile organic compounds vocs. Butyl rubber iir also called isobutylene isoprene rubber a synthetic rubber produced by copolymerizing isobutylene with small amounts of isoprene.

Safety hazards at ambient temperature are generally negligible. Below you will find general highlights on the burning processes of polymers as well as a basic overview of some of the flame testing procedures that can be performed. Valued for its chemical inertness impermeability to gases and weatherability butyl rubber is employed in the inner linings of automobile tires and in other specialty applications. Butyl rubber isobutylene with about 2 iso prene has been functionalized through the residual double bonds via the bro mobutyl intermediate to produce a material with 2 conjugated diene see fig.

In addition to tremendous shock absorption butyl features exceptionally low gas and moisture permeability and outstanding resistance to heat aging weather ozone chemical attack flexing. Mixing with basic solutions generates heat. 19 this resin shows high reactivity towards e beam or uv free radical or cationic 53 the bromo butyl intermediate has also been used to attach acrylate or photoinitiator groups to the butyl. Key advantages butyl lok sealants remain permanently flexible and form permanent bonds to a wide variety of substrates including concrete metals and plastics.

Synthetic rubber caulks and sealants are paintable with water base paints and come in clear formulas that are more transparent when cured than any other caulk. Butyl rubber offers some special capabilities to make it a potential option for applications that need quality sealing lining mounting or more. Reacts with strong oxidizing agents perhaps sufficiently exothermically to ignite the reaction products.
