For applications requiring durable, rigid, or chemically resistant sealing solutions, Boss Polymer’s Plastic P-shaped seal profiles (also referred to as ‘Plastic P profile seals’ or ‘Plastic P section seals’) offer an effective way to prevent drafts, reduce heat loss, and manage airflow. We expertly manufacture a broad range of Plastic P seals from versatile materials like PVC, Santoprene (for specific flexibility needs), and other engineering plastic compounds.

Boss Polymer is a highly trusted company with a strong reputation in the marketplace and has been supplying Plastic P seals to various industries for thirty-five years. We have the capability to provide the highest quality plastic P seals.

Choose from Standard Dies or Custom Plastic Seals

We offer a wide range of standard dies for Plastic P seals or, alternatively, our in-house engineers can custom build a plastic seal to meet your specific requirements.

Offering a Wide Range of Plastic P Seals

P and J plastic seal profiles, typically designed with a hollow bulb, achieve a balance between compressibility and structural integrity. They are inherently firmer and hardier than their sponge plastic counterparts, providing robust sealing that resists compression set in demanding conditions. The versatile flange design allows for precise positioning along edges to effectively block dust, noise, and vibration, and can also be used for secure fixing. Plastic P seals are available in specified lengths or continuous coils to suit various project requirements

Additional features of our Plastic P Seals include:

Resistant to ozone
Resistant to UV
Resistant to weathering
Resistant to heat
Prevents heat loss
Prevents leakage of gases and fluids
Exhibits excellent “shape” memory
Functions within a wide temperature range

Plastic P Seal Applications

Boss Polymer designs and manufactures a versatile range of Plastic P seals and profiles for sealing in a variety of applications where durability, rigidity, or specific chemical resistance is paramount. Common uses include:

Rigid door and window frames (e.g., UPVC windows)
Enclosures for electronics or machinery (where a firmer seal is needed)
Water gate seals and industrial fluid management (for specific chemical or abrasion resistance)
Automotive interior trims and non-dynamic seals
Dust and draft exclusion in commercial buildings
Applications requiring low friction or easy cleaning
