Question 1

What does NSB Polymers GmbH do?

Accepted Answer

NSB Polymers GmbH is a technical raw material trader specialising in plastics. Our focus is on spot materials, surplus stocks, Near Prime, Off Grade, Wide Spec, Ready in Stock and technical polymer grades for compounders, injection moulders, extruders and industrial product manufacturers.

Question 2

What materials does NSB Polymers trade?

Accepted Answer

NSB trades technical engineering plastics and standard polymers, including PA6, PA66, PBT, PET, POM, PC, PC/ABS, ABS, SAN, PMMA, TPU, TPE, PP, PE, EVA, POE and further specialty grades. Technical suitability and commercial attractiveness are always the decisive criteria.

Question 3

Is NSB a recycling company?

Accepted Answer

No. NSB is not a conventional recycler but a raw material trader. Many of the materials we offer are new or unused industrial raw materials originating from overproduction, surplus inventory, project cancellations, specification deviations or warehouse clearances.

Question 4

What does Near Prime mean?

Accepted Answer

Near Prime describes material that is very close to prime quality but may deviate in individual aspects from the standard specification. Typical reasons include minor colour deviations, limited certifications, MFI variations, residual lot character or internal downgrading by the manufacturer.

Question 5

What does Off Grade mean?

Accepted Answer

Off Grade is a technically usable plastic raw material that does not fully meet the prime specification. This does not automatically mean waste or reject material. It can represent commercially attractive goods that are very well suited for specific applications.

Question 6

What does Wide Spec mean?

Accepted Answer

Wide Spec means that one or more technical values fall within a broader range than prime material. Examples include MFI, viscosity, moisture content, colour, ash content or additive levels. For many applications, this is processable provided the customer verifies the values.

Question 7

What does Ready in Stock mean?

Accepted Answer

Ready in Stock refers to an inventory position or residual lot originating from overproduction, project completion, warehouse clearance or short-notice sale. Ready in Stock can be Prime, Near Prime, Off Grade or Wide Spec. Technical quality must always be assessed on a case-by-case basis.

Question 8

What is a TDS?

Accepted Answer

A TDS (Technical Data Sheet) describes the typical technical properties of a material — for example density, MFI, tensile strength, impact resistance, heat deflection temperature, viscosity or flame retardant class.

Question 9

What is a COA?

Accepted Answer

A COA (Certificate of Analysis) contains batch-specific analytical values. In spot trading, a COA is particularly valuable because it shows concrete lot data rather than generic type characteristics.

Question 10

What minimum quantities apply at NSB?

Accepted Answer

Minimum quantities depend on the specific offer. For spot and Ready in Stock goods, pallet quantities, part loads, containers or full truckloads are common. Some suppliers will only sell the entire lot.

Question 11

Which Incoterms does NSB offer?

Accepted Answer

Depending on the project, NSB can offer EXW, FCA, FOB, CFR, CIF, CPT, DAP or DDP, among others. The appropriate Incoterm depends on storage location, destination country, mode of transport, customs handling and risk allocation.

Question 12

Why does moisture content matter for polyamides and TPU?

Accepted Answer

PA and TPU can absorb moisture. Excessive moisture can cause bubbles, streaks, hydrolysis, viscosity degradation, poor surface quality and mechanical problems. Correct pre-drying is therefore mandatory before processing.

Question 13

Does NSB deliver worldwide?

Accepted Answer

Yes, NSB can deliver internationally, provided material, logistics, export controls, customs clearance and payment structure are aligned. Key markets include Europe, Turkey, Asia and other industrial regions.

Question 14

Can NSB guarantee that a material will work in a specific application?

Accepted Answer

No. NSB can provide technical information and empirical knowledge, but final application approval rests with the processor. Only the customer has full knowledge of the tooling, process, normative requirements and end application.

Question 15

Is Off Grade automatically poor quality material?

Accepted Answer

No — this assumption is incorrect. Off Grade simply means the material falls outside a specific prime specification. For robust applications, compounding or non-safety-critical components, it can be economically highly advantageous.
