Thermal & Protective Insulation
Thermal & Protective Insulation
Chemical processing demands materials able to withstand and function in the harshest hostile environments. If you are producing or processing petrochemicals or inorganic chemicals, pharmaceuticals, industrial gases, plastics, rubbers, detergents, paints, coatings, pigments, and many others, you are faced with an extreme temperature, and/or chemical, and/or mechanically challenging environments.
We offer the most diverse line of high temperature and chemically inert films, fabrics and flexible composites that allow you to produce, process and protect under extreme environments. We design and engineer material solutions that thrive in heated, chemically hostile, and mechanically challenging environments.

- III. Spray shields
WFlanges, valves, joints are commonly found in the processing of any chemical and can be a potential source of leaks including sprays with consequent injuries. These can be minimized with the use of spray shields commonly known as flange covers or protectors or diaper guards. Hitemp has engineered flexible, chemically inert, and resilient high temperature composites to protect you against leaks.

HiTemp offers PFA films in various width & thickness configurations starting from 1mil all the way to 16mil. FEPs (perfluoroalkoxy polymers) are widely known for their excellent dielectric properties across a wide temperature and frequency range. Known for their excellent clarity and weather resistance, FEPs have extraordinary chemical resistance and fracture resistance under high stress making them ideally suited for high performance during application as liners.. This film offers the highest continuous use temperature 260°C of any melt-processable fluoropolymer film, PFA film offers many of the performance properties of PTFE in a clear, transparent form and can be heat sealed, thermoformed, welded, metalized, or laminated to a wide variety of materials.
Our TR series is formulated and processed so as to minimize tearing if folded and to withstand creasing, therefore resulting in extended durability.
