EVA foam manufacturer excessive cracking phenomenon
DCP is a key factor in the amount of one , if the DCP dosage is too low , then the material is cross linked EVA foam manufacturer inadequate , resulting in sticky mode phenomenon . If the DCP dosage is too high, then the material is cross linked EVA foam manufacturer excessive cracking phenomenon, manifested as
[ 4 ] elasticity , tensile, tear and peel strength decreases. An appropriate amount of DCP was 017 ~ 019 parts of the elastic case, tensile, tear and peel strength is large, and the heat shrinkage ratio , compression deformation.
2. 3 EVA foam manufacturer agent
EVA foam manufacturer agent is a bubble of growth , and its direct impact on the amount of material EVA foam manufacturer magnification , EVA foam manufacturer is to control the mechanical properties of the main factors. Azodicarbonamide (ADC) is cost-effective, and wide application , widely used. With the gradual increase in ADC , EVA foam manufacturer magnification increases , the density , hardness , tensile , elastic tended to decrease . When the ADC is excessive, in the material will produce the formation of more , the larger the pores , and cause the bubble to bubble formation consolidation uniform pore size distribution , resulting in poor physical properties . ADC
