The smaller particle size can obtain better dispersed and better foaming process control and more concentratedventingtemperature area. The processing temperature of 170-190 ℃ (organic tin system takes high value, calciumzincandlead system takes low value) can achieve optimal foaming effect, in wood plastic and non-wood plastic hair of PVC.
The ratio of white foam of general product thickness of ≤ 5 mm with NH-302 and AH-616 is 1: 2-1: 1, andtheproductthickness of NH-302 and AH-616 is 1: 1-4: 1 with the best effect. Light yellow should disperse powder, decompositiontemperature 185 ± 4 ℃, gas yield 185 ± 5ml/g (STP), decomposition residue to white, odorless, canbeusedforfoaming of white products.
Foaming products can form an independent spherical bubble chamber, formingahoneycomb-like stereo structure, which can obtain a good mechanical strength.
