We are SITRAPLAS

Competence in engineering plastics

As a production company with innovative product solutions, SITRAPLAS is your industrial partner for individual compounds. At our company headquarters in Bünde, East Westphalia, we develop and manufacture high-performance plastic compounds.

Customers in the automotive, domestic appliance and electrical industries, among others, benefit from our tailor-made solutions worldwide. We offer you high-quality, unique compounds based on various base polymers, such as PC, ABS, ASA, PBT, PMMA and corresponding blends for your technical application.

Our solutions for your market

Automotive

Technologies of the future, lightweight construction, design freedom, emission reduction, sustainable materials: these are the trends that will significantly influence the development of plastics. We have been a supplier to the automotive industry for years when it comes to high-quality compound products. Let us inspire you today.

Home Appliances

They are among the products that play a fundamental role in consumers' daily lives. As a technology partner, we support our customers in this segment with the development and production of compounds for demanding domestic appliances. Our goal is to secure decisive competitive advantages for our customers.

Electrical industry

Plastics in the electrical industry have to meet special requirements, such as product safety and mechanics, but also design-relevant criteria. Our compounds satisfy the highest demands in terms of fire behavior, functional requirements and coloration. Our materials are already being used successfully in many different series applications.

Lighting technology

Many products are staged directly or indirectly by light. To control and monitor this light, it is necessary to understand the sum of waves and particles. We are able to significantly influence the effects of light with our compounds.

Free time

The sports and leisure industry places high value on the design, feel and performance of materials. The outstanding properties of our products can be specifically adapted to corresponding functionalities. Therefore, our compounds can be found in many well-known products.

Looking for EN-Light, the TF series or Green Compounds? You will find what you are looking for in our product overview.

to the product finder

EN-LIGHT

The EN-LIGHT compound product range is based on different polymers. Depending on the requirement profile, the material scatters and distributes the light or blocks it.

GREEN COMPOUNDS

Green compounds complement our product range in the areas of PC, PC+ABS, ABS, PMMA and SAN

TF-SERIES

Compounds from the TF series have particularly good tribological properties. This optimization primarily serves to improve the coefficient of friction.

TP-SERIES

Plastic compounds with exceptional properties and a wide range of applications can be found in the TP (Technical Products) series product group.

MG SERIES

In many sectors, from construction to heating technology to infrastructure for electromobility, outdoor plastics are indispensable.

CUSTOM COMPOUNDS

Customized technical compounds, tailored to the specific requirements of our customers, are an essential part of our business.

Capacity

Due to our modular production processes, we supply plastic compounds from very small quantities to large tonnages. We guarantee short delivery times worldwide. Our process monitoring is precise and guarantees the greatest possible batch and quality reliability - even when scaling up to our production facilities.

Sustainability at SITRAPLAS

With individual plastic compounds from the GREEN COMPOUNDS series, our customers receive high-quality products made from sustainable or bio-based raw materials. The first-class compounds are used in various sectors: from the automotive industry to the household appliance industry.

Building block for more sustainable compounding
Production waste is an important building block for more sustainable compounding. That is why we collect and sort the waste so that it can then be ground up and used as a valuable raw material for our GREEN COMPOUNDS.

Reuse of 92% of plastic waste
Whether virgin materials or additives, materials from the internal raw material cycle or purchased regrind from post-industrial and post-consumer waste: In our production processes, all of these products undergo close quality controls.

CO2-neutral production
We produce all our compounds using 100% renewable energy and support the EKOenergy label to promote sustainable energy production and international climate and environmental protection projects.

Energy efficiency as a declared goal
Digital and detailed: We monitor the energy consumption of our processes, such as electricity, water and compressed air, on a daily basis so that we can intervene quickly if necessary. With this in mind, our entire compounding process is optimized for energy efficiency. We not only analyze energy consumption very closely. From the screw to the BigBag - here too, we identify sustainable solutions by checking which consumables can be dispensed with or used for longer. Wherever possible, we make processes paperless.

Calculate CO2 footprint
We calculate the CO2 footprint of our plastic compounds during product development. Based on the transparent environmental impact, customers make a well-founded and sustainable choice regarding their own product applications.
