Product Description

   Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140-170°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance   Eco friendly yoga mat making machine Anti-fatigue yoga exercise matt machine High quality Yoga Mat EVA foam machine  Logo  Eco Friendly  Yoga sports Mat making machine   colorful Interlocking Soft Gym Yoga mat machine Exercise EVA Foam Mat making machine

Vulcanization with sulfur

The most common vulcanizing methods depend on sulfur. Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Accelerated vulcanization is carried out using various compounds that modify the kinetics of crosslinking;this mixture is often referred to as a cure package. The main polymers subjected to sulfur vulcanization are polyisoprene (natural rubber) and styrene-butadiene rubber (SBR), which are used for most street-vehicle tires. The cure package is adjusted specifically for the substrate and the application. The reactive sites-cure sites-are allylic hydrogen atoms. These C-H bonds are adjacent to carbon-carbon double bonds (>C=C<). During vulcanization, some of these C-H bonds are replaced by chains of sulfur atoms that link with a cure site of another polymer chain. These bridges contain between one and several atoms. The number of sulfur atoms in the crosslink strongly influences the physical properties of the final rubber article. Short crosslinks give the rubber better heat resistance. Crosslinks with higher number of sulfur atoms give the rubber good dynamic properties but less heat resistance. Dynamic properties are important for flexing movements of the rubber article, e.g., the movement of a side-wall of a running tire. Without good flexing properties these movements rapidly form cracks, and ultimately will make the rubber article fail.Comfort TPE Yoga Mat machine Non-slip Sports Fitness Pad making machine  Pilates mat making line  Fitness Mat machine Anti-skid Sports matt machine EVA  Foam mat machine EVA Yoga Mat machine   colorful Interlocking Soft Gym Yoga mat machine Exercise EVA Foam Mat making machine

Vulcanization of polychloroprene

The vulcanization of neoprene or polychloroprene rubber (CR rubber) is carried out using metal oxides (specifically MgO and ZnO, sometimes Pb₃O₄) rather than sulfur compounds which are presently used with many natural and synthetic rubbers. In addition, because of various processing factors (principally scorch, this being the premature cross-linking of rubbers due to the influence of heat), the choice of accelerator is governed by different rules to other diene rubbers. Most conventionally used accelerators are problematic when CR rubbers are cured and the most important accelerant has been found to be ethylene thiourea (ETU), which, although being an excellent and proven accelerator for polychloroprene, has been classified as reprotoxic. The European rubber industry has started a research project SafeRubber to develop a safer alternative to the use of ETU.

what is twin screw extruder 
Co-rotating twin-screw extruder : Due to the co-rotating twin-screw has the opposite speed at the meshing point, one screw pulls the material into the meshing gap, and the other screw pushes the material out of the gap, resulting in material from one screw turns to the other screw and advances in a "∞" shape. Since the gap of the meshing zone is small, the speed of the meshing screw and the groove are opposite in direction, so that the cutting speed is high, and the self-cleaning effect is good, that is, any accumulated material adhering to the screw can be scraped off, thereby The residence time of the material is very short, so the twin screw extruder is mainly used for compounding and pelletizing .

The Applications of Co-rotating Twin Screw Extruder

1.Glass fiber reinforced, fuel barrier palletizing (For example PA6, PA66, PET, PBT, PP, and PC reinforced flame retardant)
2.Highly filled material granulation (For example PE, PP filled with 75%CaCo)
3.Granulation of heat-sensitive materials (For example PVC, XLPE cable material)
4.Intense color masterbatch (For example filled with 50% color powder)
5.Antistatic masterbatches, alloys, coloring, low-fill co-mingling granulation
6.Cable material granulation (For example sheathing material and insulation material)
7.XLPE pipe material granulation (For example masterbatches for hot water crosslinking)
8.Thermoset plastic compounding and extrusion (For example phenolic resin, epoxy resin, and powder coating)
9.Hot melt adhesive, PU reactive extrusion palletizing (For example EVA hot melt adhesive and polyurethane)
10.K resin, SBS de-volatile granulation
