Norseal® BCF (Butyl Coated Foam), an efficient and cost-effective solution to the most demanding sealing applications. Norseal® BCF features the compression/deflection properties of PVC foam with the high adhesion sealing of butyl. As PVC foam is compressed, it exerts a deflection force back to maintain sealing integrity. These dual properties provide the flexibility necessary for applications with irregular contours and complex shapes. The product also resists cold without cracking

FEATURES:

• Conforms to corner radius and irregular contours
• Resists cold without cracking
• Low moisture vapor transmission rate
• Seals against water penetration
• Easy-release liner for clean application

Norseal® PVC extrusion is a PVC-based foam polymer where the foam core compresses easily to conform and fill joints. This economical solution is an attractive alternative to wet caulk sealing methods.

FEATURES:

• Provide excellent seal against light, dust and moisture.
• Long spooled lengths are ideal for long production runs.
• Cell structure of foam requires less material to achieve a positive seal.

Norseal® extrusion P-4000 series provide a faster and more economical solution to special sealing applications with balanced properties between softness and sealing properties. Thermoplastic Elastomer (TPE) based material features good recovery and heat stability showing low compression set at high temperature. Foam extrusions are available with or without adhesive, in a variety of densities, and different length to meet the needs of different applications, specially automated.

Features:

• Long spooled lengths are ideal for long production runs.
• In addition to standard product, custom made profile can be designed to meet customer’s needs.
• Soft, Low force to compress, from low density (~130 kg/m³)
• Water and air sealing properties with skin layer and cell structure.
• Elastometric properties, low compression set at high temperature.
• Pressure-sensitive adhesive available for increased versatility.
