Foam agents - Import export

Several million scrap refrigerator units are disposed of every year in Germany alone. The proportion of refrigeration units recycled by volume totals about 40% and is the most significant segment after consumer electronics. One particular challenge in this recycling process is presented by chlorofluorocarbons such as R 11, R 12 or R 141b, which were used for decades as foaming agents for insulation materials. Since these substances damage the Earth’s ozone layer when released, they must be removed and collected securely in a closed-system pre-processing plant. The fact that pre-processing of legacy refrigeration units always needs to be carried out in accordance with the latest technological standards means that plant operators gain a decisive advantage when working with an innovative and experienced plant manufacturer. With ERDWICH, you are assured of the latest technologically advanced solutions – even for the most demanding and safety-conscious refrigerator recycling. The...

Alkyl polyglycosides (APGs) are a class of non-ionic surfactants widely used in a variety of cosmetic, personal care, household and industrial applications. They are biodegradable and plant-derived from sugars and plant oils. they are, mainly, used as cleansing agents and emulsifiers. They show great foam properties of the final product. With respect to their favorable environmental profile and excellent dermatological properties (mildness, in terms of skin irritation potential), APGs attract considerable interest. Coco-glucoside is a mild vegetable-based non-ionic surfactant derived from coconut oil and glucose from corn. It is a mild cleanser used in cosmetic formularies including in products for individuals with a sensitive skin. It is recognized as a natural ingredient by the Natural Product Association. Decyl glucoside is a mild non-ionic cleanser used in cosmetic formularies including in products for individuals with a sensitive

It has alreday a high viscosity at a low concentration, it shows a stable viscosity at temperature fluctuations and is very pH-, freeze and thaw stable.

JC 640 is a release agent to pre-treat metal- and resin-molds in the field of polyurethane foam processing.

The key areas of application for this group of PU products are determined by their excellent insulation properties. As highly cross-linked foams (usually with closed cells), they are used in the construction industry, sanitation industry and also in the refrigeration industry. Typical properties Moulded part density of 35–120 kg/m³ Available foaming agents: pentane, hydrofluorocarbons (such as 365/227mfc) and water Special formulations and versions Good heat insulation (lambda value from 22 mW/mK) Spray systems – flame protection formulations Construction industry: DIN 4102 B2, Swiss V

Compact - purocast® RIM - purorim® Clear Coat - puroclear® When compact end products are the objective of the manufacturing process, PU systems without foaming agents that react under waterless conditions are used. These non-foamed polyurethanes serve a variety of casting and spray applications where excellent surface characteristics are usually important.

PU composites are mainly found in the production of moulded parts resistant to bending. The skilful combination of materials puts the topic of lightweight construction into the spotlight (honeycomb technology applications). Sophisticated surface designs are supported by corresponding PU / UP resin systems. Thanks to the reduced component weight, moulded part applications are used in the automotive sector – and, with corresponding flame protection formulations, also in rail vehicle construction.
