Segmentation by Product Type

The plastic sealing strip market is segmented into two primary product categories based on manufacturing processes:

1. Continuous Vulcanization Plastic Sealing Strip

Continuous vulcanization strips are manufactured through an automated extrusion process with continuous heat curing, resulting in uniform density and superior mechanical properties. These strips are popular for high-volume applications requiring consistent quality.

• Market Insight: This segment currently dominates the market due to its cost-effectiveness for large-scale production. Continuous vulcanization strips are widely used in automotive window and door seals where uniform performance is critical.

• Trend: Manufacturers are investing in advanced extrusion technologies to produce thinner yet more durable strips for compact electronic devices and lightweight vehicle designs.

2. Discontinuous Vulcanization Plastic Sealing Strip

Discontinuous vulcanization involves batch processing with intermittent curing cycles, allowing for more complex shapes and customized formulations. These strips typically offer better temperature resistance and can incorporate special additives.

• Market Insight: While commanding a premium price, discontinuous vulcanization strips are seeing growing demand in specialized applications such as industrial equipment sealing and high-performance construction seals.

• Trend: The ability to incorporate additives like fire retardants and anti-microbial compounds is making this segment increasingly attractive for healthcare and public infrastructure projects.
