5 facts that producers of rubber parts need to consider now (PDF available in English and Italian)
The new Drinking Water Directive KTW-BWGL brings with it numerous changes and challenges for processors of elastomer compounds. To ensure that your products made from elastomer compounds meet the legal requirements, you need to consider not only technical but also legal aspects.
Fact 1: Understanding the new legal requirements
The new Drinking Water Ordinance KTW-BWGL ensures uniform standards in the drinking water industry.
This means that all materials and components that come into contact with drinking water must be certified.
What does that mean for you?
- Without the required certificates, products made of elastomer for drinking water components can no longer be placed on the market with legal certainty.
- Proof of conformity with the new regulation requires documents such as test reports, test certificates and certificates.
Our tip:
Work with suppliers who already provide you with certified elastomer compounds and all the necessary certificates. This saves you time and simplifies the production process.
Fact 2: Select the right mixtures for easy processing
The processability of elastomer compounds is important for efficiency in your company. Poorly processable compounds often lead to increased production waste, higher costs and frustration within the team.
What should you look out for?
-
Elastomer compounds should be stable and easy to mold.
-
Problems such as bubble formation, adhesion problems or uneven hardening can be avoided by using high-quality mixtures.
Our tip:
Use specially developed mixtures that are suitable for drinking water applications. Suppliers who offer process tests can give you additional security.
Fact 3: Certifications - Be prepared now
Compliance with the new KTW-BWGL drinking water regulations is not possible without the right certification. As a processor, you must ensure that your materials and components meet the requirements.
What do you need to know?
-
The KTW assessment basis requires toxicological assessments and migration tests.
-
Providers who already offer shortened certification procedures can help you avoid delays.
Our tip:
Rely on partners who can not only supply you with the blends, but also the necessary certifications. This will help you avoid cost-intensive conversions in the production process.
Fact 4: Saving time through fast supply chains
Delays in the supply chain can significantly affect your production. The rapid availability of materials is particularly important for last-minute changeovers or urgent projects.
What does this mean for your production?
-
Delayed deliveries can lead to downtimes and missed deadlines.
-
Providers with high availability and short response times ensure your flexibility.
Our tip:
Work with suppliers who keep large quantities in stock or can produce at short notice. Clarify in advance whether express deliveries are possible.
Fact 5: Individual advice pays off
The processing of elastomer compounds for drinking water components is complex and every project has individual requirements. Expert advice can help you avoid mistakes and achieve optimum results.
Why is this important?
-
Expert knowledge helps you to find the best material combinations and parameters for your systems.
-
Advice on specific problems saves time and money
Our tip:
Take the opportunity to get advice directly from your suppliers. Suppliers who work with you on solutions can become valuable partners in the long term.
