What We Do

Chemistry that becomes performance

Jasmino's compounding laboratory develops custom rubber formulations engineered to specific performance requirements — chemical resistance, temperature range, abrasion resistance, hardness, and compression set.

Our library of 2,000+ proven formulations spans the full elastomer spectrum: natural rubber, butyl, EPDM, neoprene, nitrile, CSM (Hypalon), silicone, and fluoroelastomers (FKM/Viton).

Every compound is tested in our in-house laboratory before production — tensile, elongation, hardness, ageing, and chemical immersion testing to verify performance against your specific service conditions.

Elastomer Families

The full spectrum of rubber chemistry

Each elastomer family offers distinct advantages for specific environments.

NR — Natural Rubber

Abrasion · Resilience · Tear

Highest abrasion resistance and resilience. Ideal for mining, mineral processing, and mechanical applications.

AbrasionMiningMechanical
IIR — Butyl & Chlorobutyl

Chemical · Gas Impermeability

Outstanding resistance to mineral acids and gas permeation. The primary elastomer for chemical lining applications.

Acid ResistanceGas BarrierLinings
EPDM

Ozone · Weather · Steam

Excellent ozone, weathering, and steam resistance. Used for outdoor exposure, hot water, and polar chemical service.

OzoneSteamWeathering
FKM — Fluoroelastomers

Universal Chemical · High Temp

Near-universal chemical resistance at temperatures up to 250°C. For the most demanding sealing and protection applications.
