Sika has the longest experience in production of flexible PVC membranes globally. And Sika is the only international manufacturer with a production line in China. Local production means short lead times also for very big projects and special membranes.

Production

Sika started the local production in China in 1998. Since 2005 the production runs on a state of the art co-extrusion line in Shanghai. The membranes produced in Shanghai serve the Chinese market but are also exported to Asia Pacific, India, Middle East and Europe. The production process is certified according to ISO 9001 and ISO 14001.

Quality Control

The QC at the Shanghai production site has all the equipment and dedicated specialists to test the Sika Sarnafil flexible PVC membrane in accordance with GB standard but also foreign standards (EN, ASTM, JIS). The QC lab is certified according to CNAS (China National Accreditation Service for Conformity Assessment) which qualifies it for third party testing. Sika conducts regular field studies as part of the overall QC process to evaluate the performance of installed roofing systems over the years.
