Abstract:
      The environmental performance of chlorosulfonated polyethylene rubber（CSM）pucker tarpaulin and methyl vinyl silicone rubber（referred to as silicone rubber） pucker tarpaulin used in gangways of railway vehicles was researched.The results showed that the heating mass loss of CSM pucker tarpaulin was 2.86 g·m-2，while that of silicone rubber pucker tarpaulin was 2.52 g·m-2.Soluble lead and soluble cadmium were not detected in both type of pucker tarpaulins.The total volatile organic compound（TVOC） emission of CSM pucker tarpaulin was 3.369 mg·m-3，whereas the TVOC emission of silicone rubber pucker tarpaulin was 1.040 mg·m-2，and formaldehyde was not detected in both tpye of pucker tarpaulins，therefore silicone rubber pucker tarpaulin presented better environmental performance.This research could provide a reference for the selection and on-board application of rubber pucker tarpaulins used in the gangways of railway vehicles.
