The Next Generation of Phenolic Insulation

Teqtix Phenolic Solutions BV is the proud developer and manufacturer of the Next Generation Phenolic product range, including the Insulphen, Firephen and Rhinophen products. With years of extensive research and based on the experience of a dedicated team, we have managed to improve the traditional phenolic foam characteristics dramatically. Our new formulas result in lightweight foam productsthat offers superior thermal, fire, smoke and mechanical properties.


Lightweight and cost-effective alternative for fire protection applications.

Due to the unique combination of characteristics, the phenolic products from Teqtix can be used for a much wider range of applications. The Firephen product has successfully proven to be a more lightweight, cost-effective alternative to the traditional insulation that is used as core material for fire doors, composite panels, internal and external walls and facades. Compared to the other ‘high performance plastic foams’ like polyurethane (PUR) and polyisocyanurate (PIR) foam, the smoke emission in fire behaviour testing is extremely lower, making it nearly incombustible.

High strength with minimal weight.

Traditional phenolic foam is known to be more fragile than other types of high performance insulation foam. This is due to the fact that the cell structure under stress will have less ability to bend, extent or contract leading to collapse of the individual cell wall. At Teqtix Phenolic Solutions, we are able to produce high density blocks (120 – 160 kg/m3) offering sufficient mechanical strength for most applications. Also, we have thoroughly invested in testing the effect and impact of adding various kinds of glues and coverings onto our products. The load capacity and strength of a combined panel of Rhinophen foam, even at low density like 40 kg/m3 and 60 kg/m3 combined with a thin laminate is extremely high and rigid.

The tale of corrosion and phenolic insulation.

Corrosion under insulation can always occur under any type of thermal insulation material and it’s complex to understand given the mix of corrosive elements on the pipe and the assortment of metals (stainless steel, copper steel, carbon steel and others). Corrosion requires high temperature, oxygen, moisture and a concentration of corrosive ions. Modern phenolic insulation has less than detactable halogens, and in a properly designed and installed system there should neither be moisture nor oxygen. In our experience, all insulation failures are due to either improper installation of product or misapplication (i.e. poor specification) of a product – not the insulation itself.

In significant temperature drops condensation is always a risk. Condensation, leading to water entrapment, will degrade the insulation properties.
