  • Description

The Solid Silicone P-Profile is a durable sealing strip made from high-quality solid silicone rubber. Its P-shaped cross-section features a rounded compression bulb and a flat mounting base, providing reliable sealing, cushioning, and gap filling. Designed for applications requiring firm compression force and long service life in demanding environments.

Key Features:

  • Solid construction – Offers higher compression force compared to foam versions; ideal for pressure-sensitive seals.

  • P-shaped cross-section – Rounded bulb provides consistent compression; flat base ensures stable mounting.

  • Wide temperature range – Operates from -50°C to +200°C (-58°F to +392°F).

  • Low compression set – Maintains sealing force even after long-term compression.

  • Excellent aging resistance – Resists UV, ozone, and weathering; suitable for indoor and outdoor use.

  • Chemical resistance – Withstands mild acids, alkalis, oils, and many industrial chemicals.

  • Flame retardant options – Available in UL94 V-0 or HF-1 rated grades.

  • Non-toxic & odorless – Compliant with RoHS and REACH; food-grade options available.

Typical Applications:

  • Door and panel seals for industrial enclosures, electrical cabinets, and control boxes

  • Automotive engine compartments, hoods, trunks, and doors

  • Sealing for machinery, vibration dampers, and access covers

  • Household appliances (refrigerators, dishwashers, washing machines)

  • HVAC systems, ventilation ducts, and cleanroom equipment

  • Protective edging and bumpers on equipment
