Characteristics of Phenylvinyl Raw Rubber
Phenylvinyl raw rubber is a special rubber material with excellent physical and chemical properties:
Solubility: Insoluble in water, but soluble in organic solvents such as toluene.
Mechanical Properties: Low compression set, excellent resistance to saturated vapor pressure.
Temperature Adaptability: Suitable for high and low temperature environments, and can be made into sealing materials resistant to high and low temperatures.

Protective Properties: Can be used to manufacture waterproof and moisture-proof insulation materials; physiologically inert.
Chemical Stability: Resistant to ozone, electric arc, corona, and weathering.
Military Application Material Requirements for Cable Outer Sheaths
Military cables have specific material requirements for their outer sheaths, primarily including:
Mechanical Protection: Sufficient mechanical strength and abrasion resistance are required.
Environmental Protection: Excellent corrosion resistance, waterproofing, and moisture resistance are required.
Electrical Performance: Specific electrical characteristics must be met.
