  • Description:

FS-210 butyl sealant is a kind of single-part, solvent-free, 100% solid content, primary seal hot melt sealant for insulating glass. It has high adhesion in extrensive temperature.The butyl sealant has excellent adhesion to glass, aluminum, galvanized steel and stainless steel. Benefit from its extremely vapor penetrability, it has excellent anti-humidity system when it work together with other sealant .It can be used for the manufacture of insulating glass units. Together with an elastic sealant compound like silicone, polyurethane or polysulfide sealant, they form an excellent dual-seal system.

The FS-210 butyl sealant for first sealing of insulating glass, if you are interesting one-station butyl sealant of insulating, we recommand our FS-221 series. 

  • Usage method:

Contact surface must be clean, dry and free of grease. the sealant can be applied by butyl extruding machine (extruder) of special hot melt butyl sealant of IG production line. Its concrete condition can be achieved by adjusting temperature and pressure. The preferred range of temperature is 100°C to 150°C. The operating environment temperature is recommended not to be lower than 10°C.

butyl rubber sealant


Butyl rubber is a synthetic rubber, a copolymer of isobutylene with isoprene. Polyisobutylene, also known as "PIB" or polyisobutene, (C4H8)n), is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based. Butyl rubber is produced by polymerization of about 98% of isobutylene with about 2% of isoprene. Structurally, polyisobutylene resembles polypropylene, having two methyl groups substituted on every other carbon atom. Polyisobutylene is a colorless to light yellow viscoelastic material. It is generally odorless and tasteless, though it may exhibit a slight characteristic odor.


Butyl rubber has excellent impermeability, and the long polyisobutylene segments of its polymer chains give it good flex properties.

The formula for PIB is: -(-CH2-C(CH3)2-)n-

It can be made from the monomer isobutylene or CH2=C(CH3)2 only via cationic addition polymerization.


A synthetic rubber, or elastomer, butyl rubber is impermeable to air and used in many applications requiring an airtight rubber. Polyisobutylene and butyl rubber are used in the manufacture of adhesives, agricultural chemicals, fiber optic compounds, ball bladders, caulks and sealants, cling film, electrical fluids, lubricants (2 cycle engine oil), paper and pulp, personal care products, pigment concentrates, for rubber and polymer modification, for protecting and sealing certain equipment for use in areas where chemical weapons are present, as a gasoline/diesel fuel additive, and even in chewing gum. The first major application of butyl rubber was tire inner tubes. This remains an important segment of its market even today.
