Raw Natural Rubber Sheet is produced from freshly tapped natural rubber latex, featuring superior elasticity as well as outstanding shock absorption and cushioning properties. It delivers remarkable DIN abrasion resistance, resisting rapid thinning under long-term frictional contact and greatly extending the service lifespan of shoe soles. The material maintains reliable anti-slip performance on both dry and wet surfaces, effectively lowering slip risks for casual footwear, sneakers and safety work shoes. 

Boasting excellent low-temperature resistance, it will not stiffen or lose elasticity in cold outdoor conditions. It offers stable vulcanization compatibility and works well with rubber compounding agents, color masterbatches and reinforcing fillers. The slab features a dense internal structure free of air voids, enabling clean die-cut edges without rubber crumbs during cutting and molding. 

Formulated with anti-aging components, it slows yellowing and oxidation during prolonged storage and outdoor usage. Its wide adjustable hardness range supports manufacturing of lightweight soft soles and heavy-duty labor shoe soles. Made of non-toxic, low-odor natural ingredients without harmful plasticizers, the sheet complies with mainstream global environmental standards for footwear and food-contact applications. Serving sole manufacturers, shoe material factories and rubber processing plants, this pure natural rubber sheet acts as a vital elastic raw material. 

It can be manufactured into casual shoe soles, running sneaker outsoles, anti-slip soles for safety footwear, slipper bottoms, soft children shoe soles and lining cushion for boot bottoms within the footwear sector. It is also applicable to daily necessities including rubber mats, silent floor mats, anti-slip table mats, elastic grips and household shock-absorbing parts. Additional application scenarios cover industrial conveyor belt linings, mechanical shock pads, anti-vibration rubber blocks and sealing gaskets, sports accessories such as yoga mat base layers, elastic liners for knee protectors and shock-absorbing components for sports equipment, as well as luggage hardware parts including rubber liners for silent luggage wheels, elastic anti-collision pads and wear-resistant gaskets for bag bottoms.

Before layout marking and die cutting, lay the natural rubber sheet flat on the cutting table for 15 minutes to release internal stress. Conduct small-scale vulcanization sample testing to verify formula compatibility before mass compound production of shoe soles. Avoid excessive stretching during unwinding and cutting, which may cause uneven thickness and inconsistent elasticity of finished soles. 

Vulcanization temperature and duration should be properly controlled; excessively high temperature leads to rubber aging and elasticity loss. Wrap leftover rubber slabs with dust-proof PE film after daily processing to prevent oxidation and discoloration under sunlight. Sustainable raw material management is implemented: raw materials are sourced from certified eco-friendly rubber plantations with low-impact latex tapping techniques to prevent over-logging and preserve tropical ecological balance. Long-term fair trade contracts with local rubber farmers guarantee stable income for agricultural workers. The molding workshop adopts waste heat recovery systems, cutting coal and power consumption by over 25% compared with conventional rubber production lines. 

All manufacturing wastewater undergoes multi-stage sedimentation, filtration and recycling with zero direct discharge into natural water sources. Environmentally friendly packaging is adopted: degradable PE wrapping film for rubber sheets, and export cartons made of 100% recycled corrugated cardboard printed with water-based ink, eliminating non-degradable auxiliary plastic packaging to reduce plastic waste across the supply chain. We cooperate with professional rubber recycling enterprises to build scrap recycling channels. 

All cutting leftovers are collected centrally for secondary desulfurization and reproduction, minimizing natural rubber waste and reducing the carbon footprint of the shoemaking and rubber industries. Free of hazardous heavy metal additives, the raw material formula meets EU REACH, California Prop 65 and international footwear environmental standards, safeguarding workshop workers’ respiratory health and end consumers’ wearing safety and realizing eco-friendly production from raw materials to finished products. Officially named Raw Natural Rubber Sheet, this product is made of 100% pure crude natural rubber without recycled rubber adulteration. 

Its core strengths include high rebound performance, superior wear resistance and reliable anti-slip properties on dry and wet surfaces for durable shoe soles. Hardness can be customized within Shore A 55~75 to produce soft casual soles and heavy-duty safety soles. Apart from shoe sole production, it is widely used for daily mats, industrial shock pads, sports accessories, luggage anti-slip gaskets and more. The material features good low-temperature resistance and maintains stable elasticity without hardening in cold environments. Featuring low odor and non-toxic composition, it passes major international export environmental certifications. For proper storage, place sheets flat in cool shaded warehouses away from direct sunlight and high temperature, and keep packaging film tightly sealed to avoid aging and discoloration.
