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. Typical properties Moulded part density of 450–1100 kg/m³ Fibre proportion from 30 % Available foaming agents: usually water Reinforcing materials Glass fibre rovings Glass fibre mats and non-crimp glass fibre fabrics Carbon fibres Natural fibres (hemp, sisal, coconut etc.) Special formulations and versions Honeycomb materials for sandwich structure components Paper honeycombs Waterproof paper honeycombs (patent-pending process) Plastic honeycombs Aluminium honeycombs Systems with a large processing window Use of polyols based on renewable resources Self-parting with simultaneous good lamination properties Flame protection formulations Automotive: FMVSS 302 Rail vehicle construction: DIN 5510 (S4, SR2, ST2) Aircraft construction: FAR 25853, ABD 0031 Construction industry: DIN 4102 B2

Flexible foams are elastic PU foams that are used in many different applications thanks to their usually excellent padding properties. In addition to the seating furniture industry, applications include motor vehicle and rail vehicle seats. However, they can also be used in seals and loaded damping components. Typical properties Moulded part density of 40–250 kg/m³ Adjustable compression load deflection Dimensional stability under heat up to 100°C Water is usually used as the foaming agent, but liquid CO2 is also possible Special formulations and versions Viscoelastic Barium sulphate loaded for acoustic applications, e.g. in aviation FIPFG seals for PU high-pressure processing Dimensional stability under heat up to 150°C in special applications Emission-free pursuant to RAL-ZU 38 Flame protection formulations Automotive: FMVSS 302 Rail vehicle construction: DIN 5510 (S3, SR2, ST2), EU TL 45545 Aircraft construction: ABD 0031, FAR 25.853 Furniture industry: California 117 Section A Part 1

This group of polyurethane products typically features a lightweight foam core with a compact, dense skin – the so-called integral skin. Thanks to these properties, PU soft- / semi-rigid integral skin foams cover a broad range of applications such as steering wheels, shifter knobs, arm rests, protective pads, floor mats and operating room rests. Typical properties Moulded part density of 220–600 kg/m³ Shore A hardness of 10–90 Available foaming agents: pentane, hydrofluorocarbons (such as 365/227mfc) and water Good abrasion resistance Special formulations and versions Viscoelastic Anti-static Flame protection formulations Automotive: FMVSS 302 Rail vehicle construction: DIN 5510 (S4, SR2, ST2), EU TL 45545 Aircraft construction: ABD 0031, FAR 25.853 Construction industry: DIN 4102 B2 Recreation industry: M2, UNI 9175/87 (= CSE 4/83): class 1.IM, BS 5852 crib 5
