Differentiation of polyurethane elastomers manufactured by P+S from other elastomers on the market

Compared to other elastomers, in particular rubber grades, P+S polyurethane elastomers offer a wide range of
technical advantages. These include:

Polyurethane elastomer production and manufacturing processes

The production of polyurethane elastomers is a precise and controllable process that has a high level of material expertise
and requires technical expertise. At P+S, we rely on flexible low-pressure casting systems And on to the tried and tested
Hot casting process for producing compact and microcellular polyurethane elastomers.

In contrast to classic injection molding processes — which are used for thermoplastic polymers — our
Proceedings on the Reaction of liquid raw material componentsthat react under controlled conditions. Through the exact
Controlling temperature, mixing ratio and demolding time, we achieve high-quality, homogeneously reacted molded parts with
reproducible quality.

Raw materials and components

The selection of raw materials plays a central role in the performance of the subsequent component. For the production of our
We work with polyurethane elastomers with a variety of high-quality components that allow targeted adjustment of
Material properties enable:

• Isocyanates How to form NDI (naphthalene 1,5-diisocyanate), TDI (toluene diisocyanate) and MDI (diphenylmethane diisocyanate)
  together with the polyols, the backbone of polyurethanes. These substances react with polyols to form long-lasting, elastic
  structures.
• polyols: Depending on the area of application, we use polyester, polyether or polycarbonate polyols. These influence
  Properties such as hydrolysis resistance, recovery behavior and media resistance. Within these groups are
  numerous types of polyols with different chain lengths and functionalities are available.
• Networker: Various chemical crosslinkers are used to specifically control crosslinking density —
  either on a petrochemical or bio-based basis.
• additives: By adding specific additives, polyurethane elastomers can be further individualized:
  • colorway
  • antistatic agents
  • anti-microbiotics
  • Hydrolysis protection
  • Glide enhancer

This modular selection of raw materials makes it possible to create a tailor-made property profile for every application — economically and sustainably at the same time.

Polymerization processes

At the core of material production is polyaddition: A chemical reaction in which the isocyanates and polyols are added
from crosslinkers, additives and, if appropriate, propellants react to form a solid, elastic plastic. The exact control of this
Reaction is essential for the reproducibility of product properties.

Polyurethane elastomer injection molding techniques

‍

‍P+S does not process polyurethane elastomers by injection molding. Our focus is on low-pressure casting and hot-casting processes, which can be used to produce significantly more individual molded parts and higher material properties — even in small series and special formats.

Polyurethane elastomers in the transportation industry

Polyurethane elastomers meet high load capacity and durability requirements in the transportation industry. The P+S materials offer tailor-made solutions for transport applications that enable efficient power transmission and vibration damping.

Polyurethane elastomers in the engineering industry

Polyurethane elastomers are in demand in mechanical engineering due to their adaptability and robustness. They withstand high temperatures and aggressive environmental influences. They are suitable for a wide range of applications, from seals to high-volume dampers.

‍

Polyurethane elastomers in agricultural industry

Technical components made of polyurethane elastomers are particularly popular in the manufacture of agricultural vehicles and machinery, as they are extremely robust and chemically resistant. They are resistant to moisture and microbes and can withstand the harshest conditions.

Sustainability and environmental aspects

Sustainability is not a trend, but part of our responsibility — even in the production of high-performance polyurethane elastomers. Our solutions not only impress with their technical performance, but also with a resource-saving and future-oriented development approach. The high robustness and long lifespan of our polyurethane elastomers ensure sustainable use in a wide range of applications. Where possible, we use bio-based raw materials and only use REACH and RoHS compliant components and coatings. In addition, a large proportion of the energy used for production comes from alternative sources. Ours EcoVadis certification confirms our commitment to transparency, responsibility and sustainability along the entire value chain.

‍

recycling options

The recycling of polyurethane elastomers is only technically possible to a limited extent. Nevertheless, we are constantly working on innovative solutions to extend the life cycle of our materials. One example of this is Upcycling foam waste, which are reused in other industrial systems. The vast majority of retired elastomers are currently used as a energy recovery supplied — a process in which thermal energy can be recovered and used efficiently.

Energy efficiency in production

The production of polyurethane elastomers is associated with a high energy requirement, as high temperatures are required during processing. Nevertheless, we are able to make our use of energy more and more efficient. With heat exchangers throughout the production process valuable process heat is recovered. At the same time, we cover a large part of our electricity consumption alternatively produced energy. Even the complete conversion to LED technology The lighting of our production facilities contributes to increasing energy efficiency.
