Excellent Waterproof Performance EVA300 and EVA500 for Low Temperature Conditions
Product Introduction
Polymer composite adhesive waterproof coiled material is a new synthetic polymer waterproof coiled material with excellent waterproof performance, which use EVA synthetic polymer composited sheet, high polymer copolymer,High quality modified asphalt as basic material. With the waterproof performance of both polymer material and adhesive material, a layer of material, two fortification. Greatly improving the waterproof performance, allowing construction under the condition of low temperature and damp environment, good adhesive sealing, puncture resistance and self-healing ability, high elongation. Product is avirulent insipidity, ROHS compliance.
