                                            Mega sealing strips series can be used in window and door profile, auto and so on.     Our products meet the requirements of REACH, ROHS, PAHS, POHS, SONY 00259 etc. We can promise there are no heavy metals such as lead, barium, mercury, cadmium and so on.     The products have excellent weatherability, UV-resistance, flame-resistance, solvent, oil, chemical, alkali, alcohol resistance. The migration are very low. And the low temperature performances are very good, so they can be used in cold area and high-rise building.     We can adjust the formulation according to the customers’ requirements, such as hardness, flame-retardant, UV-resistance etc. ♦ Variety Colours ♦ Workshop show ♦ Company Certifications: ◊ ISO 9001:2008 ◊ ISO 14001:2004 ◊ Certification of UL
