PRACTICAL KNOWLEDGE FOR PLASTICS PROS
Answers to the most frequent questions on material selection, food contact, chemical resistance and processing – manufacturer-neutral and grounded in Swiss manufacturing practice.
At a glance
Our guides answer the recurring material and application questions from purchasing, engineering and planning – well-founded, manufacturer-neutral and grounded in Swiss everyday practice. Instead of product advertising they offer decision support: which plastic withstands which chemical? Which material is food-grade under EU 10/2011? Which welding process suits PP, PE-HD or PVC-U? Each article orders the relevant criteria, compares the candidate materials and names the associated standards and approvals. The recommendations are deliberately phrased with caution – what is always decisive is the product-specific data sheet and the declaration of conformity for the concrete article. Semadeni processes technical thermoplastics in-house; this hands-on knowledge feeds the guides. For the concrete design of a component or a conformity record, our specialists in Ostermundigen and Vienna advise application-specifically.
All guides
Which question are you facing?
Knowledge from practice
Manufacturer-neutral decision support
Material and process comparisons by suitability rather than by range – so the choice matches the application, not the stock.
Practice from our own manufacturing
Injection moulding, thermoforming, hot-gas welding and CNC machining in-house – the guides reflect what really holds up on the shop floor.
Standards and approvals placed in context
EU 10/2011, LFGB, REACH/RoHS and autoclavability per EN 285 – explained clearly and product-related rather than blanket.
Cautious rather than categorical
Values serve as guideline figures for preselection; what is decisive is the data sheet for the concrete article – no invented suitability promises.
From the guide to the fact sheet
Each article links to the matching material and standard fact sheets – from the overview straight to the detail.
Advice rather than a dead end
If a question stays open, our specialists in Ostermundigen and Vienna advise application-specifically and supply semi-finished or finished parts.
Frequently asked questions about our guides
Who are the guides intended for?
For buyers, design engineers and laboratory or operations managers who need to make a well-founded preselection quickly. The articles are built manufacturer-neutral and name criteria, material comparisons and standards – as orientation before the concrete technical design.
Do the guides replace technical advice?
No. They order the criteria and narrow the choice, but they replace neither a product-specific data sheet nor a declaration of conformity. For binding material release or a standards record we advise application-specifically.
How do I find the right material fact sheet?
Each guide links directly to the materials covered – such as PP, PE-HD or PMMA – and to the relevant standards like EU 10/2011. Alternatively you will find all fact sheets in the materials and standards overview.
Are the stated values binding?
The values are typical guideline figures for preselection and can vary by type, formulation and manufacturer. Decisive is always the data sheet for the concrete article; for food contact or dangerous goods, additionally the product-related declaration of conformity or approval.
How often are new guides added?
We expand the offering along the most frequent enquiries – material selection, chemical resistance, food contact and welding processes. If a topic that concerns you is missing, get in touch; often the next article grows out of it.
Your question isn't covered?
Describe your application – service temperature, media contact, required approvals – and our specialists recommend the matching material or the right process. We supply semi-finished or finished parts and provide the necessary records. Personal advice from Ostermundigen and Vienna.
