LaTeX reclaimed rubber is the best choice to reduce the cost of raw materials by replacing natural rubber production rubber products, especially some low latex containing latex reclaimed rubber, can significantly reduce the cost of raw materials. For example, the use of low latex content reclaimed rubber to produce sponge foam strips can significantly increase economic efficiency.

However, when using latex reclaimed rubber to produce low-cost foaming tapes, once the formulation of the sponge foaming tape is unreasonable, there will be problems such as poor elasticity and poor tear resistance of the regenerated rubber foamed rubber strips. The elasticity and tear resistance of the latex containing low amount of rubber itself are lower than that of natural rubber. Therefore, the amount of latex reclaimed rubber, the amount of foaming agent and various chemical additives in the latex regenerated rubber foam rubber strips are reasonably designed. Coordination is very important. Xiao Bian today shared with you a low-cost formula for the production of styrofoam bars using latex reclaimed rubber:

Latex reclaimed rubber, 100 parts; Zinc oxide, 4 parts; SA, 4 parts; Clay, 70 parts; N550, 20 parts; Paraffin oil, 10 parts; Vaseline, 5 parts; foaming agent H, 6 parts; urea, 5 Parts; CaO, 5 parts; S, 1.3 parts; Accelerator, 2 parts; Accelerator D, 1 part; PZ, 0.5 parts; 233.8 parts in total.

If you want to improve the processability and improve the plasticity of latex reclaimed rubber foam strip products, you can add a certain amount of softening oil to the reclaimed rubber product formula; if the cost allows, you can also add a small amount to the formula. Natural rubber, such as smoke tablet rubber and latex reclaimed rubber, improves the rubber content and elasticity of latex reclaimed rubber foam rubber strips, prolongs the service life of foamed rubber strips, and the ratio of natural rubber and latex reclaimed rubber is about 1:6. Good; In the actual production, in order to improve the comprehensive performance of latex reclaimed rubber foam strips, you can also choose a slightly higher latex content of reclaimed rubber, to increase the proportion of reclaimed rubber, reduce the amount of natural rubber, the same can reduce the sponge hair Bubble production costs.

In reclaimed rubber products, latex reclaimed rubber is not the only choice for raw materials for styrofoam, and other types of reclaimed rubber can be used in the production of styrofoam, among which the styrofoam produced by EPDM reclaimed rubber is resistant to high temperatures. It is excellent in weather resistance, ozone resistance, and aging resistance. When used in various outdoor applications, the sealing effect is good and the service life is long.
