Plastics matched to your process.
Send us your enquiry and tell us what the material is for. We propose a suitable material — virgin, recycled or off-grade — or, where no standard grade fits, a blend or modification worked out with a plastics technologist. Availability and terms are confirmed with the supplier for each enquiry; suitability for your part is confirmed in a trial.

What SEMANAT does
SOURCING
Market search by specification and application.
SELECTION
A material proposal based on your part, process and requirements.
BLENDS
Where no standard grade fits: a proposed blend or modification, worked out with a plastics technologist.
SUPPLY
One-off lots or recurring supply, on terms agreed for each enquiry.
You don’t need to know the exact grade
Tell us what you make, how you process it and what the finished part has to do. That is enough for us to start selecting or sourcing a material.
Useful details to start with:
- process: injection moulding / extrusion / blow moulding
- MFI / MFR
- colour
- stiffness and impact strength
- service temperature
- GF / filler
- virgin / PIR / PCR
- quantity and delivery location
Not every set of requirements can be met by a single material. We will tell you plainly what is realistic and where a compromise, a blend or a modification would be needed.
From application requirements to material on your line
Three levels of support — choose where you want to start.
Material sourcing
We source materials by specification, processing method, application, volume and budget — from a single lot to a recurring stream.
Application matching
We start from your application and product requirements, not from a trade name.
Material selection and blend recommendations
With a plastics technologist, we look at modification options for your part. We develop material or blend proposals based on your requirements. Availability and supply arrangements are confirmed individually.
Material groups we work with
The groups below show where we source and select materials — they are not a guaranteed stock list. We confirm availability and specifications for each enquiry.
PA / engineering plastics
- PA6, PA66
- reinforced grades
- application-specific grades
GF / mineral-filled compounds
- glass-fibre reinforcement
- mineral fillers
- modified materials
Regranulates and regrinds
- PIR / PCR
- industrial lots
- recurring streams
Off-grade / surplus / non-standard lots
- off-grade, near-prime
- surplus stock
- powders, additives, non-standard lots

From enquiry to delivery in 5 steps
Need
We get to know your application and requirements.
Material
We propose a material — or a blend where no standard grade fits.
Qualification
Documents, a sample or a trial in your production — as the case requires.
Offer
We confirm availability, quantity and terms with the supplier.
Delivery
A one-off lot or regular supply.
Have material to offer?
Regranulate, regrind, off-grade, surplus stock or a recurring material stream? Send us the key parameters and the volume available.
When a standard grade is not enough
An off-the-shelf grade will not suit every application. Together with an experienced plastics technologist, we analyse what the application requires and propose a modification or a blend formulation. A proposal is a starting point for trials, not a finished compound; whether it is produced, and by whom, is agreed case by case.
Need more stiffness, better impact strength or the right glass-fibre content for a specific part? A question like that is a good place to start.
Examples of what we work on:
- PA6 / PA66
- GF reinforcement
- PP compounds
- mineral fillers
- impact modification
- processing properties
- mechanical properties
- application-specific formulations
We confirm the scope of work, and whether a solution is feasible, case by case.
What makes SEMANAT’s approach different
Not tied to a single product catalogue
We search the market — producers, distributors and industrial lots — rather than fitting your requirement to one product list.
We talk about your application, not just a grade name
We start from what your product and process require. The trade name is the outcome, not the precondition.
Sourcing backed by technical know-how
Material selection and blend proposals are supported by an experienced plastics technologist who works with SEMANAT.
