Thermo-Impact insulation is a type of press insulation that minimizes heat loss by preventing heat from transferring from the die to the body of the press. Its high mechanical strength and excellent insulation property allow it to be used in press applications where energy savings are critical. Here are some examples of why thermal insulation is an important component of a press. Whether replacing the tooling or the entire machine, thermal insulation is an important component in operation.
The BIBS HP type of thermal insulation is an economical combination of BIBS and spray polyurethane foam. Mineral and rock wool are two types of insulation materials available. Rock wool is made from natural minerals, and slag wool is made from blast furnace slag. Mineral wool is made from up to 75% post-industrial recycled content and does not require chemicals for fire resistance. Both types of insulation are available as blankets or loose-fill insulation.
Choosing the right insulation material is critical. When choosing a material for high-temperature thermal insulation, ensure that it is compatible with the operating environment and equipment requirements. The materials used must be capable of enduring the thermal demands of the machine and the production process. This means that the manufacturer of thermal insulation should provide a chart that will guide you through the selection process. If you’re unsure, consult with an insulation expert.
Fiberglass is another good option. It is strong enough to withstand high temperatures yet does not corrode metals. It’s the cheapest press insulation material but offers excellent structural strength and minimal shrinkage. Additionally, it’s odorless and can withstand temperatures as high as 2192o F. Despite its price; fiberglass is the most common choice for insulating a press. If you’re looking for a more durable insulation material, consider CMS wool, which is marginally more expensive than fiberglass but is odorless and will not corrode metals.

Siempelkamp also developed a method to combine two-component fibers with wood fibers. The technique reduces the amount of special fibers needed. It is also tested on a four-foot (1200mm) pilot and field plants. The method works well on both flexible and rigid polyurethane boards. Different thicknesses, densities, and sizes can be produced with this method. The Siempelkamp dry manufacturing process is unique in its method.
NanoPore(TM) Thermal Insulation is another type of press insulation, and it is a proprietary blend of nanoporous materials with superior insulating properties. This insulation material can withstand temperatures of 330°F and 200°C, which is more than five times higher than conventional foam insulation materials. Prime Tech supplies quality Thermal insulation for presses at reasonable prices. It can be manufactured in metal or other impermeable skins, or the end user can purchase its inserts.
Polyurethane is a thermoset foam insulation material that is available in two forms. One form has dense cells filled with gas, and the other is spongy and contains air. Its R-value is lower than that of EPS, but it does offer greater durability. Polyurethane foam is more expensive than EPS and has higher fire resistance. If you choose polyurethane insulation, make sure you choose one that is non-HCFC-gas-free.
Another popular form of Thermal Insulation is cellulose. It contains about 75-85% recycled paper fiber and is composed of post-consumer waste newsprint. About fifteen percent of the material is made from recycled plastic and is treated with borate, the flame-retardant used in cellulose insulation. Because it has no oxygen, it limits fire damage and is environmentally friendly. Cellulose has an R-value of between three and seven.
