PROPERTIES:
ADC is a nitrogenous organic foaming agent for various rubbers such as CR, EPDM, IIR, NBR(NBR/PVC) and SBR, especially for tiny and uniform pored products. ADC powder has a relatively high foaming temperature (200-210℃), which can be effectively reduced by addition of small amount of foaming activators. It will not promote abnormal odor of foaming products.
APPLICATION:
Various foam rubber products.
USAGE:
1-10phr usually.
PACKING & STORAGE:
Net weight 25kg/Carton lined PE bag; Net 600 kg/pallet.
Shelf-life: 1 year in its original packaging on conditions of lower temperature(< 35℃) and drying(< 50% RH)
Compared to traditional ADC powders, YLSCH ADC-75 allows:
Dust free products with 6-8µm mean size grains of ADC, production environment improver.
Lower decomposition temperature and effective guarantee of activity of ADC due to pre-dispersed masterbatch and special formula.
Tack free products at room temperature, convenience and accuracy on ingredients.
Lower Mooney viscosity at lower temperature (50℃), higher quality of dispersion, homogeneous apertures of foam products.
Wider compatibility with other elastomers.
