What Exactly Is PVC Sealing Stip?

PVC Sealing Stip is a flexible, gap-filling strip made from polyvinyl chloride, designed to block air, water, dust and noise for seams of different facilities. As the most widely used general-purpose sealing product in 2026, it balances performance and cost far better than many higher-priced alternatives for non-extreme working conditions.

The industry consensus is that PVC sealing stip with Shore A hardness between 35-55 meets 90% of common civilian sealing demands.

Main Profile Types on The Market

Common profiles include D-type, P-type, E-type, O-type and special customized shapes. 2026 market data shows that D-type PVC sealing stip takes up 58% of the sales volume, as it fits the gap of 2-5mm perfectly for most home door and window seams.
