Improved Cure Characteristics: Halogenation increases the rubber’s ability to undergo vulcanization more efficiently with different curatives, especially with sulfur-based curing systems. This results in faster curing and better crosslinking properties.
Enhanced Adhesion: The introduction of halogens improves the adhesion properties of the rubber, especially to other materials like metals and fabrics, making it ideal for products that require bonding.
Better Heat Resistance: Halogenated butyl rubber has superior resistance to heat, ozone, and weathering compared to non-halogenated butyl rubber. This makes it suitable for use in high-temperature environments.
Permeability: Like regular butyl rubber, halogenated versions maintain excellent impermeability to gases, particularly air and moisture. This is important for applications such as inner tubes and tire liners, where maintaining air retention is crucial.
Chemical Resistance: Halogenated butyl rubber is resistant to many chemicals, acids, and alkalis, which extends its utility in environments where chemical exposure is a concern.
Application of Halogenated Butyl Rubber
Automotive Industry:
Halo butyl rubber is widely used in tire inner liners, hoses, and other automotive components due to its excellent air retention, durability, and heat resistance.
01
Pharmaceutical Industry:
Its low permeability makes it suitable for pharmaceutical stoppers and seals, especially in the storage of sensitive drugs that require controlled environments.
02
Adhesives:
It is often used in pressure-sensitive adhesives and sealants due to its ability to bond well with various materials.
03
Construction:
Halogenated butyl rubber is used in roofing membranes, sealants, and other construction materials that require good weather and chemical resistance.
04
Protective Coatings:
Its resistance to weathering and chemicals makes it a good candidate for use in protective coatings.
05
Material of Halogenated Butyl Rubber
Isobutylene (or 2-methylpropene):
This forms the bulk of the polymer chain, providing the rubber's fundamental structure and low gas permeability.
Isoprene:
A small addition of isoprene introduces unsaturation (double bonds) into the polymer, allowing it to be vulcanized (cross-linked) for enhanced strength and durability.
Transportation
Whether it is air freight, express delivery, or sea freight, we can arrange shipments according to the time required by customers. We help customers inquire about the best rates and arrange the delivery of your goods in the most economical way. This allows you to control the schedule of the entire project to meet seasonal cargo demand.
