NEOPRENE (Chloroprene Rubber) Product Overview
NEOPRENE is a versatile synthetic rubber introduced in the early 20th century and validated by over half a century of industrial use.
Originally developed to overcome the poor oil resistance of natural rubber, its unique balance of properties keeps it widely used across the globe.
Excellent oil & chemical resistance: Highly resistant to waxes, fats, lubricants, and most petroleum products
Good resistance to alkalis and diluted acids/salts: Stable in diluted mineral acids and inorganic salt solutions
Weathering & ozone resistance: With suitable formulation, provides long-term UV and aging resistance
Water resistance & burial stability: Can be submerged or buried long-term without corrosion or degradation
Stable physical strength: Good flex resistance, twist resistance, and low compression set
High-temperature resistance: Continuous use at 80–95°C, intermittent up to 120°C (formula-dependent)
Does not melt at high temperatures; excessive heat may cause hardening or loss of elasticity
Low-temperature resistance: Usable from –20°C to –25°C with only minor property changes
Special grades can operate in –55°C extreme cold
NEOPRENE is widely used in industrial, construction, transportation, electronic, and consumer products, including:
Wire & cable jacketing
Industrial gaskets, hoses, belts, tapes
Construction sealants, structural bearing pads
Foam products (e.g., wetsuits, insulation pads)
Adhesives, coatings, sealants
Automotive, industrial machinery, agricultural equipment
Extruded & molded products
Footwear, paper industry, packaging products
Comonomer: None
Highest bonding strength (ideal for contact adhesives)
Mooney viscosity: 50–60
Very fast crystallization rate
Contact-type adhesives (yellow glue / CONTACT cement)
