Getzner solutions add elasticity in areas affected by vibrations. This prevents them being transferred and becoming a problem. The critical factor is achieving precisely the right level of vibration dampening. Does the vibration need to be absorbed or redirected into the system? What different frequencies occur? How much elasticity can there be in the system without influencing its stability and statics?
Solving these challenges requires a carefully tailored range of elastic materials.

Frequently asked questions
Polyurethane, PUR, PU – what does it all mean?
Polyurethane is a versatile plastic known for its high elasticity, abrasion resistance and chemical resistance. The abbreviation PUR stands for polyurethane and is often used in technical applications. PU is the international short form and is mostly used in product descriptions and standards. All three terms refer to the same material, which is produced by a chemical reaction between a polyol and an isocyanate.
How are polyurethane elastomers made?
Polyurethane is produced by a chemical reaction between a polyol and an isocyanate, usually in the form of a diisocyanate. By carefully controlling the degree of cross-linking, materials with a range of properties can be produced – from elastic polyurethane elastomers to high-strength PU rubbers.
We manufacture elastic polyurethane products on our production lines as sheets (which can then be stored and transported as rolls) and as moulded parts for complex shapes, helping to minimise waste.
How durable is polyurethane?
Polyurethane (PUR/PU) is impressively durable. The material is highly abrasion-resistant, elastic, and can easily withstand mechanical stresses such as compression and impact.
Our polyurethane materials exhibit good resistance to oils, grease, aqueous solutions and other influences such as micro-organisms. All information on our chemical resistance can be found in the datasheet.
How is polyurethane recycled?
Mechanical recycling enables polyurethane and other engineering plastics to be remade into products for vibration isolation and shock protection. PU foams, separated by type as purely as possible, are first shredded. These ‘PU chips’ can then be easily stored for use in the next stage of the production process. The resulting PU granulate is then mixed according to a precise formulation, homogenised and blended with a binding agent. This material is then pressed into the final granulate sheet. The fine dust generated from shredding the chips is collected and fed into the chemical recycling process as a raw material.
In chemical recycling, PU materials are converted into high-quality recyclates under controlled conditions. Using an optimised energy process, we can now extract polyols that match the properties and functionality of the original source materials obtained from the fossil-based primary raw materials.
