Designed to address the dual challenges of extreme low temperatures and corrosive environments in the chemical industry, our low-temperature toughening agents deliver robust solutions for critical components such as pipelines, storage tanks, and seals. Elastomer-based products (e.g., silicone rubber, SEBS, TPV) combine a broad operating range (-100°C to 250°C) with resistance to acids, alkalis, and oils, ideal for seals, protective coatings, and dynamic parts. Nanofiller-enhanced agents (nano-silica, carbon nanotubes) not only improve impact resistance in engineering plastics but also integrate conductive/thermal properties, perfect for anti-static equipment and ultra-low-temperature sealing. Eco-friendly options (epoxidized soybean oil, polyester plasticizers) ensure low-temperature flexibility in food-grade packaging and cable sheaths while meeting strict safety standards. Customizable solutions like ionomers and liquid rubber enhance crack resistance in epoxy-based materials, extending the lifespan of tank linings. Rigorously tested for chemical compatibility, dynamic fatigue resistance, and long-term stability, our product line empowers chemical equipment to operate safely and durably in harsh, low-temperature corrosive environments.

Silicone Rubber
Extreme Environment Seals: Ideal for chemical processing equipment in Arctic/polar regions where temperatures drop below -70°C. Used in reactor flange gaskets, pump shaft seals, and cryogenic storage tank liners.
Special Note: Avoid continuous exposure to concentrated sulfuric acid or steam above 150°C. Best specified with 40-60 Shore A hardness for optimal cold flexibility.
SEBS (Hydrogenated Styrene-Butadiene Block Copolymer)
Chemical Transfer Systems: Perfect for flexible connections in acid/alkali dosing systems operating at -30°C to 60°C. Used in:
• Diaphragm valves for bleach solutions
• Expansion joints in pH adjustment systems
• Laboratory tubing for chilled reagent transfer
Processing Tip: Compounder should use 15-25% SEBS content when modifying PP for chemical resistance.
TPV (Dynamically Vulcanized Elastomer)
Moving Parts in Chemical Plants: Specified for:
• Agitator shaft seals in pigment production (-20°C to 110°C)
• Butterfly valve seals for chilled brine systems
• Conveyor belt scrapers in fertilizer plants
Maintenance Note: Shows 3x longer service life than EPDM in ozone-rich environments.
TPU (Thermoplastic Polyurethane)
Oil & Gas Applications: Critical for:
• Subsea umbilical sheathing (-40°C seawater)
• Hydraulic seal rings in LNG facilities
• Wear strips on drilling mud processing equipment
Grade Selection: Use ester-based TPU for fuel resistance, ether-based for hydrolysis resistance.
Liquid Isoprene Rubber (LIR)
Composite Tank Construction: Applied as:
• 5-8% additive in epoxy liners for sulfuric acid storage tanks
• Impact modifier for FRP scrubber components
• Flexibilizer for cryogenic adhesive formulations
