POLYETHYLENE FOAM PE - Closed cell foam rubber, PE foam
PE cell foam is a good insulator against hot and cold and creates a sound reduction insulation. It may be used in a variety of different weather conditions. PE sealants stop air infiltration and are used to seal window glass into wood, aluminium and plastic frames. PE foam is also used as a packaging foam.
Ultrafoam FBE consists of a Fusion Bond Epoxy corrosion barrier, spray applied polyurethane foam overcoated with an adhesive or bonding film followed by a durable high density polyethylene jacket. This polyurethane foam insulation system is designed to provide excellent thermal insulation and corrosion protection characteristics.
pipe joints to maintain the insulation level of the pipeline from low to high operating temperatures In situ polyurethane insulation for joints Straight pipes and fittings are laid down and are then welded to ensure tightness of the inner circuit. Once the inner pipe is joined and welded the operators can place an
Polyethylene foam is a strong and resilient closed‐cell foam, ideally suited as a shock‐absorbing material in packaging and padding. Polyethylene closed‐cell foam is available in sheets, cylinders, and tubes that are great for expansion joint filler (backer rod), insulation, buoyancy components, and
Polyurethane foam insulated steel pipe also referred as urethane foam pre-insulated piping, PU district heating pipes is the insulation pipe with rigid polyurethane foam plastic as its insulation material, made of inner carrier steel pipes, middle rigid polyurethane foam insulation
Rovanco's High Density Polyethylene (HDPE) Jacketed System is designed for piping systems above or below ground suitable for inside or outside applications. High quality polyurethane foam insulation combined with a durable watertight jacket supplied in 20' or 40' random lengths, means an economical, high-quality system.
Heat-Tite® - Pre-Insulated Pipe • Thermal Pipe Systems
Mar 15, 2018 · The system is produced with a Ductile Iron double grooved coupling containing high temperature rubber ‘V’ rings. Insulation is a thermally efficient polyurethane foam with a ‘K’ factor of 0.16 at 70ºF. The heavy wall PVC or HDPE casing and heat

Duc-Tite® - Pre-Insulated Pipe • Thermal Pipe Systems
Mar 15, 2018 · Duc-Tite is a easy to install, energy efficient quality piping system with a push-on type joint. The carrier pipe is Class 51 for 3” and 4” and Class 50 for 6” through 18” ductile iron pipe. Insulation is a thermally efficient polyurethane foam with a ‘K’ factor
foam insulation preventing any ingression of water at the jacket/ foam interface. 2.4 Straight run joints are butt fusion welded and field insulated using urethane foam to the thickness specified and jacketed with heat shrink tape. Joints can be made beside the trench or inside the trench.
Fiberglass pipe wrap kits are also easy and economical. The kits contain a roll of the fiberglass plus a plastic vapor barrier as an overwrap for extra insulation. Multi-purpose fiberglass rolls work as additional insulation in colder areas for extra protection. Foil and foam insulation is the simplest, one-step way to insulate pipe. The thin, self-adhesive foam with aluminum foil backing is used by just pressing it into

What is polyurethane insulation? - Huntsman Corporation
Polyurethane is formed by mixing an isocyanate, such as methylene diphenyl diisocyanate (MDI)with a polyol blend. These components are mixed to form a rigid, cellular foam matrix. The resulting material is an extremely lightweight polymer with superior insulating properties. Insulation products, based on MDI,
