One corpus, not thirty pages

Nexam vs. Perstorp

One sells building blocks to formulators, the other a finished masterbatch to converters. Where the two Swedish chemical companies touch, and where they never meet.

Nexam vs. Polykemi

Not a competitor but the archetype of the customer: a compounder whose cheapest alternative to chemistry is adding more virgin resin.

Nexam vs. Trelleborg

Both Swedish, both called polymer companies, and that is the entire overlap. What Trelleborg actually does, and why it sits on the buying side.

California AB 793: PCR Mandate Guide for Plastic Bottles

California's recycled content mandate for plastic beverage bottles: 15, 25 and 50 percent, a twenty cent per pound shortfall penalty, and what it shows about how Europe's version will bite.

EU PPWR Compliance Guide: 2030 & 2040 Recycled Content Targets

What Regulation (EU) 2025/40 actually requires: the recycled content minimums for 2030 and 2040, the conditions that can move them, and what Nexam Chemical claims about closing the performance gap.

HDPE Recycling Explained

How HDPE is recycled, what fails on the second pass, and what the European recycling numbers and the 2030 mandate mean for a company selling additives into that gap.

High-Temperature Polymers for Aerospace & Defense

The other half of Nexam Chemical: polyimide crosslinkers and a composite resin, sold into formulators rather than converters, and invisible in both the news flow and the segment reporting.

How a Reactive Terpolymer Changes HDPE

What that class of chemistry does to recycled polyethylene, and the gap between it and what Nexam Chemical actually discloses about its own products.

Mechanical vs. Chemical Recycling

What each process does to the polymer, why only one of them creates a market for reactive additives, and which European rules are still unwritten.

Medical-Grade Polymer Additives & Color Masterbatches

The previous site claimed a medical-grade product line. We checked the company's own pages and found none, so this page records what we looked for and what the category would require.

PCR Packaging Guide

What has to be true for a package to be fully post-consumer, what breaks first in each process, and why food contact does not follow automatically.

PET Closures & rPET Masterbatches

The cap is a different polymer with a harder specification, the lowest regulatory band and the thinnest supply. A late market, not an early one.

Plastic Market

Europe's share of global plastics production has halved since 2006 and its circular share has stalled, while recycled content becomes compulsory. What that combination means for a supplier.

Polypropylene (PP) Recycling Guide

Recycled polypropylene is the least predictable polyolefin feed, and the one where Nexam Chemical publishes no named product.

Reactive Terpolymers vs. Conventional HDPE Additives

A reactive additive competes against diluting with virgin resin, and that alternative is free until recycled content becomes a legal minimum.

Recycling

The terms the rest of this library uses: mechanical and chemical recycling, post-consumer content, intrinsic viscosity, melt strength, chain extension, contact-sensitive packaging.

Recycling Routes Compared: Prevention, Mechanical, Chemical, Recovery

Prevention, re-use, mechanical, chemical, energy recovery: the waste hierarchy applied to plastic packaging, and which single route creates demand for additives.

rPET for Textile Fibers & Filaments

Most recycled PET becomes fiber, and spinning is the least forgiving thing you can do with it. Why Nexam sells a separate linear grade here, and why textile demand is a weaker driver than packaging.

rPET Packaging Guide

Recycled PET has to pass two separate tests, food law and physics, and only one of them is what an additive supplier sells against.

rPET Packaging Masterbatch Selection

The questions that separate rPET additive suppliers, written after a week of failing to verify published claims: ask for the test, the declaration and the loading.

rPET Packaging Masterbatches for Thermoforming

Why recycled PET sheet sags in the thermoformer, what a reactive additive is meant to do about it, and which of Nexam Chemical's performance claims carry a document behind them.

Running 100% PCR Blown Film

Why a bubble made of recycled polyethylene collapses, what converters do about it today, and which of the additive claims come with published evidence.

Where Reactive Recycling is proven in production

The seven production processes Nexam Chemical claims its recycling additives work in, what evidence each claim carries, and which customer announcements stand behind them.

Advanced Materials for the Space Economy, Aerospace & Defense

The other half of the company: crosslinkers and composite resins for temperatures ordinary plastics cannot survive, invisible in both the news flow and the segment reporting.

Circular Plastics: Additives, Recycling & EU Regulation

Plastic does not come back the same as it left. The guides on what degrades, what the rules now demand, and where the gap between the two is a business.

HDPE Recycling

Recycled polyolefins lose melt strength before they lose anything a data sheet would show. What we have written on HDPE and PP recycling, and the numbers behind the market.

Recycled Content Regulation: EU PPWR, US State Mandates and Compliance

Europe conditions market access on recycled content; California puts a price on missing it. What each rule requires, and which parts are still unwritten.

rPET & Polyester: Intrinsic Viscosity, Packaging, Closures and Fibers

One polymer, several markets, and a chemistry that helps in sheet and hurts in fiber. The rPET guides, and the two distinctions worth keeping straight.

Swedish Industrial Innovation: Chemicals, Cleantech & Deep Tech

A small chemistry company between the resin producers and the converters, set against three Swedish names it is often listed beside but does not compete with.
