Butyl reclaimed rubber is made from recycled butyl rubber inner tubes, retaining the basic performance characteristics of butyl rubber. It offers excellent airtightness, low air permeability, good heat resistance, ozone resistance, and aging resistance, high damping performance, and a certain resistance to weak acids, weak alkalis, water vapor, and other media. It can replace some butyl rubber products and effectively reduce raw material costs. What specific applications does butyl reclaimed rubber have in rubber products?
1. Application of butyl reclaimed rubber in automotive tires
Butyl reclaimed rubber has excellent airtightness and is widely used in the airtight layers of automobiles, motorcycles, bicycles, agricultural vehicles, and load-bearing tires. The dosage ratio of butyl reclaimed rubber ranges from 10% to 60%, and some rubber inner tubes can even fully use butyl reclaimed rubber.
Rubber inner tube manufacturers typically use butyl reclaimed rubber together with natural rubber or butyl rubber. Reasonably blending butyl reclaimed rubber into natural rubber inner tubes provides good elasticity and mechanical strength for the inner tube, while reclaimed rubber improves the tube's airtightness and reduces costs; Producing rubber inner tubes by combining butyl rubber with butyl reclaimed rubber can reduce raw material costs, improve rubber flowability, and enhance vulcanization efficiency while ensuring inner tube airtightness.
2. Application of butyl reclaimed rubber in sealing products
Butyl reclaimed rubber has excellent airtightness, water tightness, and aging resistance. It is used in the production of flange gaskets, pipeline sealing rings, waterproof seals, and industrial rubber gaskets. It can be used alone E5LYY1218 or combined with butyl rubber, EPDM rubber, and natural rubber. Using butyl reclaimed rubber in rubber sealing products not only reduces raw material costs but also enhances the product's resistance to moisture penetration, especially improving aging resistance under long-term static sealing conditions.
3. Application of butyl reclaimed rubber in shock-absorbing rubber products
Butyl rubber molecular chains have high internal resistance, converting mechanical energy into heat when subjected to external vibrations, offering excellent damping and shock absorption performance. They are widely used in automotive shock absorbers, mechanical cushioning pads, soundproof rubber sheets, and shockproof rubber blocks. Butyl reclaimed rubber retains the basic performance characteristics of butyl rubber and can be used alone or combined with butyl rubber to produce damping and shock-absorbing rubber products, effectively reducing raw material costs.
Damping pads made mainly from butyl reclaimed rubber combined with calcium carbonate, talc powder, plasticizers, and other materials have excellent adhesion and shock absorption. They are widely used in automotive sheet metal parts, door linings, or chassis, effectively absorbing body vibrations, reducing driving noise, and do not leak in high temperatures in summer or fall off in cold winter.
4. Application of butyl reclaimed rubber in waterproof materials
Butyl reclaimed rubber has excellent airtightness and water tightness, good aging resistance, and is used for waterproof membrane production in roofs, basements, and subway tunnels. It provides excellent waterproof sealing and is not prone to brittle or cracking; It can also be used in the production of building sealing strips and insulating glass sealants, maintaining good sealing effects over a long period. In the production of self-adhesive waterproof membranes, butyl reclaimed rubber can be used as the main material, effectively reducing raw material costs.
Compared to butyl virgin rubber, butyl reclaimed rubber has lower Möni viscosity, better fluidity, and wettability, significantly enhancing the surface adhesion among waterproof tape and substrates such as concrete and metal, ensuring long-lasting sealing of building structures.
5. Application of butyl reclaimed rubber in industrial rubber products
Butyl reclaimed rubber has good airtightness, resistance to hot air aging, and steam aging. It can be used alone or combined with butyl rubber and EPDM to produce industrial rubber conveyor belts, heat-resistant hoses, heat-resistant rubber sheets, rubber pads, anti-slip pads, etc., reducing production costs. In actual production, butyl reclaimed rubber is generally prioritized when airtightness and moisture-proof requirements are met; Reasonable use of butyl reclaimed rubber in heat-resistant industrial rubber can maintain good performance for a long time at higher temperatures and is less prone to thermal aging and hardening.
When producing different types of rubber products using butyl reclaimed rubber, manufacturers need to select the appropriate reclaimed rubber according to actual needs, reasonably determine the dosage ratio, and appropriately adjust the formula and production process parameters to effectively reduce raw material costs and production energy consumption while ensuring the performance and lifespan of the finished product.
