Polychloroprene Rubber

POLYCHLOROPRENE RUBBER This product is a non-pollutant type chloroprene rubber of medium crystallization rate ,a variety of general purpose rubber , made by polymerizing the emulsion with petroleum sodium sulfonate as disperser and non-sulfur modifier as modifier as modification agent, and similar to American Type W and Japanese Type M40 polychloroprene rubber. 1. Characteristics: This product is characterized by excellent storage stability, process ability and safety property , and its products have sunlight resistance, oil resistance, chemical reagent resistance and combustion retardancy as well as heat resistance and less compression deformation. But its vulcanization rate is slow and should be solved by adjusting the vulcanization. 2. Specifications a. Appearance: Creamy flaky or lumpy Technical index Item Index Tearing strength Mpa min 14.7 Tear extensibility % min 700 Tension set max 20 Plasticity 0.4-0.6 Mooney scorch MS1+5120 min 13 Heating loss % max 1.5 Ash content % max 1.3 Mooney viscosity ML1+4100 CR2321 35-45 CR2322 45-55 CR2323 55-65 3. Application: It can used for manufacturing oil-resistant rubber hose and rubber boards, cable jackets, rubber sealing parts, etc, and is also widely used in making adhesive.
