Freudenberg Performance Materials Group (Germany) has mastered the core technology for producing sheath-core structured, thermally bonded cross-linked polymer backings. It supplies over 500 million square meters of backings annually to the global high-end waterproofing membrane manufacturing industry. In 2018, Xiniupi Waterproof Technology Co., Ltd. signed a strategic cooperation agreement with Freudenberg Performance Materials Group, and successfully developed a dedicated polymer backing for it

Xiniupi has pioneered the "CPS Reactive Adhesion Patent Technology" that reaches internationally advanced standards, with over 120 valid authorized patents to date. Its flagship products are CPS Reactive Adhesion Wet-laid Waterproofing Membranes and CPS Waterproof Sealing Paste, which can be constructed on concrete substrates in harsh environments such as dampness and contamination. A synergistic bonding effect of chemical cross-linking and physical tenon-and-mortise is formed between the waterp
