Detailed description
It features a unique CIIR+EPDM rubber compound formula. The ultralow gas permeability of chlorinated butyl rubber (CIIR) combined with the excellent thermal aging resistance of ethylenepropylenediene monomer rubber (EPDM) greatly reduces medium vapor loss of the hose during operation and significantly extends its service life. Boasting outstanding UV resistance, ozone resistance and weatherability, the hose maintains stable performance even under longterm outdoor service. Reinforced with polyester or aramid fibers, with a working pressure of over 1.2 MPa.
Product Application
Data centers, personal PCs, automobiles, projectors, new energy vehicles, charging piles, etc.

CIIR Compound: Thermal Aging Superiority
Chlorinated butyl rubber (CIIR) represents a significant advancement over standard butyl rubber (IIR) for applications where prolonged thermal exposure is a primary concern. The chlorination process introduces additional crosslinking sites that enhance the polymer's resistance to thermal degradation:
Vapor Permeation Performance: CIIR vs. IIR
The chlorination process in CIIR creates a denser, more tortuous diffusion path for gas molecules. This results in measurably lower permeation rates for coolant vapor:
The lower permeation rate is particularly important for closed-loop cooling systems where coolant concentration must be maintained over years of operation without topping up.
CIIR Hose Installation Considerations
- Minimum bend radius: Same as 102 series. The CIIR cover's higher modulus provides slightly better kink resistance in tight routing scenarios.
- Fluid compatibility: Identical to IIR+EPDM - PG25, EG30, deionized water, phosphate ester. CIIR offers marginally better resistance to hot water immersion (>90°C continuous).
Frequently Asked Questions
Q1: What is the difference between CIIR and IIR - is CIIR worth the premium?
A: CIIR offers 5-10% lower vapor permeation and 30% better thermal aging retention compared to IIR. For systems operating below +80°C with periodic maintenance access, IIR is cost-effective. For continuously heated systems (>+100°C) or sealed systems requiring minimal coolant loss over 10+ years, CIIR provides meaningful total cost of ownership savings.
