Frequently Asked Question
Do you have any question?
Halogenated butyl rubber combines ultra-low gas permeability with excellent chemical inertness, preventing drug adsorption, leaching, or oxidation. Its superior resealability after needle puncture ensures multi-dose vial integrity—critical for vaccines and biologics. Chambroad's medical-grade compounds comply with USP Class VI and EU pharmacopeia standards.
While both offer low permeability, halogenated butyl rubber undergoes chlorination or bromination to enhance cure compatibility with unsaturated elastomers (like NR or SBR), enabling co-vulcanization in multi-component seals. This expands formulation flexibility for complex industrial applications.
Yes. Our ISCC PLUS certified halogenated butyl rubber is produced using pyrolysis oil from end-of-life tires, creating a closed-loop "tire-to-tire" circular economy. This allows customers to achieve >80% sustainable content in finished products—without compromising performance or regulatory compliance.
Key sectors include pharmaceuticals (vial stoppers, syringe plungers), automotive (tire inner liners, fuel system seals), industrial manufacturing (chemical-resistant gaskets), and food contact applications (chewing gum base, bottle liners). Chambroad tailors compounds to each sector's unique demands.
Absolutely. Our R&D team—backed by 1,100+ specialists and 5 national research platforms—offers bespoke formulation services. Whether you need enhanced heat resistance, faster cure kinetics, or specific regulatory certifications, we co-develop halogenated butyl rubber solutions aligned with your performance and compliance targets.
Our production systems are ISO 9001, ISO 14001, and ISCC PLUS certified. Medical-grade compounds undergo rigorous testing for extractables, leachables, and biocompatibility. Full technical data sheets, COAs, and regulatory support documentation are provided with every halogenated butyl rubber shipment.
