LNP™ ELCRIN™ W1000XiQ Compound

Positive Plastics KIT3

What is it?

A general-purpose unreinforced PBT compound containing a minimum of 56% Post-Consumer Recycled (PCR) materials. A large volume of waste Polyethylene terephthalate (PET) is used as recycled feedstock by the beverage industry. However, not all PET is of sufficient quality to recycle into new bottles. The proprietary iQ technology, a chemical upcycling process developed by Sabic, can help convert leftover PET into new building blocks for Polybutylene terephthalate (PBT).  It allows for processing of various post-consumer recycled PET sources, including ocean-bound and land-sourced PET. It forms the basis for the LNP™ ELCRIN™  W1000XiQ compound.

Material properties

  • Tensile Modulus, 1 mm/min: 2550 MPa (ISO527)

  • Tensile Stress, yield, 50 mm/min: 56 MPa (ISO527)

  • Tensile Strain, break, 50 mm/min: 140% (ISO527)

  • Izod Notched Impact Strength, +23°C: 4kJ/m2 (ISO 180/1A)

  • Density 1.21 g/cm³ (ISO 1183)

  • Melt Volume Rate, 250°C/2.16 kg: 21 cm3/10min (ISO 1133)

Technical benefits

This compound has properties and processing profiles similar to unfilled virgin PBT equivalents. PBT rates high in resistance to several major chemical categories: Mineral Acids, Organic acids, Oxidizing agents, Organic solvents, and Petroleum.


Look and feel

PBT is noted for its durability and ductility. This compound offers a similar look as a virgin (100% fossil oil derived) unfilled PBT.


Environmental benefits

SABIC’s chemical upcycling process converts various post-consumer recycled PET sources – including grades unsuited for use in the beverage industry – to PBT resin. For every 1 kg of this compound produced, 82 PET bottles of 500 ml are recycled instead of incinerated or discarded in the ocean or landfills. This compound has a Social Responsibility Certification across the entire value chain. Compared with virgin PBT, it shows a reduction of 27% in Global Warming Impact and a 41% lower Cumulative Energy Demand. The PCR content is certified by SCS Global.



This compound offers a potential drop-in solution for conventional PBT and other alloy materials with similar applications in industries such as electronics and electrical, consumer products, healthcare, and automotive.

Consumer Goods

Why we chose this material 

The valuable feedstock from recycled bottles should be used on high-quality products rather than in the fashion industry. PBT is a versatile engineering plastic. For example, compared with polyamide, sustainable grades are not easy to find. We are happy to present this option in our kit.


Why you should consider this material

  • You want to find a sustainable high-quality alternative for virgin PBT.

  • You are looking for a prime quality material that is also recycled.
