WL-2201 Specification: Appearance: pale yellow to yellow flake Ash (%): 0.1 Softened point (): 80 / 95 Application: WL-2201 is a vulcanizing agent of natural rubber and various synthetic rubber (such as butylbenzene, chlorobutyl, butyronitrile and butyl), in particular to a rubber vulcanizing agent which is difficult to vulcanize due to the unsaturation. The invention is mainly used for manufacturing tires, joints, seals, transmission belts, food containers and the like, and can be directly added into the rubber material during mixing, and the vulcanizing agent has excellent high heat resistance, high pressure resistance and aging resistance. Package:25 kg kraft paper inner lined with plastic bag Storage: Flaked phenolic resin should be stored in dry, ventilated and cool places (below 20 ) to avoid direct sunlight and stay away from heat sources. The storage period is 6 months (below 20 â??). Note: this product can be customized according to customer requirements WL-2203 Specification: Appearance: yellow/ light brown sheet or particle softening point ():80-105 hydroxymethyl content (%):% 1.0 min acid value (mgkoh/ g):55-10 Loss on heating 1.0 max.ash (%):0.1max. Application:Wl-2203 is a tackifier for natural rubber and synthetic rubber (such as butylbenzene, butyl, butyronitrile, triethylacrylate). Can be used for producing tires, belts, hoses, food containers, gaskets and soles, and the like. The resin can reduce the Mooney viscosity of the sizing material, improve the self-adhesive property of the sizing material, improve the physical and mechanical properties of the sizing material and the thermal aging property, and has no adverse effect on the vulcanized rubber. Package:25 kg kraft paper inner lined with plastic bag Storage: phenolic resin should be stored in dry, ventilated and cool places (below 25 ) to avoid direct sunlight and stay away from heat sources. The storage period is 1year. Note: this product can be customized according to customer requirements Phenolic resin WL-2302 Appearance:dark brown flake or granular
