EPDM recycled rubber is an ideal raw material for producing sealing strips, especially door and window sealing strips, which can not only reduce the cost of raw materials, but also guarantee the sealing performance of the products. When using EPDM reclaimed rubber to produce seals, the following points should be noted:
1, EPDM recycled rubber raw material selection: good raw materials is the basis for ensuring product quality. The manufacturer who chooses EPDM reclaimed rubber to produce sealing strips is mostly producing door and window sealing strips. Therefore, when selecting raw materials, it is necessary to pay attention to the high and low temperature performance of the products. If possible, you can take EPDM recycled rubber products. Samples, a comprehensive performance test of reclaimed rubber, to determine whether the product meets the performance requirements of the seal.
2. Formulation design: EPDM reclaimed rubber is the rubber used for the recycling of waste EPDM products. The product itself contains a certain amount of softeners. When using EPDM reclaimed rubber to produce sealing tape design formula, the moisture content, relative density, contained softener and other factors of the reclaimed rubber product must be taken in consideration, and the amount is appropriately increased or decreased. The sulfur and other compounding agents are considered according to the content of the rubber hydrocarbon. The correct amount to achieve the desired effect.
3, product size design: The role of the sealing strip is sealed, noise, thermal insulation, etc., if the product size is not right, there is a gap in the installation, then not to mention the seal, not to mention the other role, the sealing strip product size design Particularly important. Therefore, manufacturers must strictly implement the quality system, such as: strict quality control of the key dimensions of seal products, 50-meter batch of products, 10-fold magnification inspection of seal strips, and monitoring of quality control charts. management.
4. Add raw rubber: When using EPDM reclaimed rubber to produce sealing strips, if you want to improve the performance of sealing strip products, you may consider adding a small amount of EPDM rubber to achieve better results and more. Long service life. EPDM reclaimed rubber + EPDM rubber is also a common way for rubber products manufacturers to produce EPDM rubber products.
The EPDM reclaimed rubber with high and low temperature resistance, aging resistance, corrosion resistance, good elasticity and high strength is the ideal raw material for producing sealing strips. The white-gray EPDM reclaimed rubber can also be used to produce light-colored or colored sealing strips.
