DIVINYCELL - PET FOAM CORE MATERIALS

Divinycell – Thermoplastic, recycled and recyclable PET foam core materials suitable for many applications

The Diab PET foam core portfolio is suitable for a wide range of applications. Divinycell PET can be processed with most common manufacturing methods including closed moulding such as RTM and infusion, and at elevated temperature processing with prepreg.

The thermoplastic Divinycell PET foam core series comes in several grades, all using recycled PET plastics for a circular approach, reducing carbon footprint and saving environment. 

PET foam core material can be made from different raw material base, PET from post-industry and post-consumer recycling. We at Diab use both types for best performance of the product and the demand of the product in the final application. 

Divinycell PR is a recyclable sandwich core, based on post-consumer PET combined with post-industrial PET to enhance 
performance. Designed as a circular solution, it meets modern environmental demands while delivering reliable mechanical properties. With good compression and shear performance, 
high dimensional stability at elevated temperatures, and low resin uptake, Divinycell PR ensures strength, durability, and processing efficiency across a wide range of applications.

Our high performance Divinycell PL has been developed with the aim of optimizing PET cored composite structures. Based on post-industry recycled PET providing excellent mechanical properties and very low resin uptake helping customers achieve weight reduction and overall cost reduction of components without surface treatment, while ensuring reliable and strong peel strength. 

Divinycell PA is a fully recyclable, cost-effective PET foam core 
developed for semi-structural sandwich composite applications 
in automotive, mobility, industrial, and construction markets. 

Other typical features of latest Diab PET foam core grades are good temperature resistance and inherent insulation properties. The higher density range is suitable for replacing wood since having closed cells and very good screw retention.

Divinycell PET can be treated with all Diab standard finishing options and supplied as pre-cut kitted foam.

FAQ about PET foam core materials

What is Divinycell PET foam core?

Divinycell PET is a thermoplastic foam core made from recycled PET plastics and used in sandwich composite structures. It provides lightweight strength, insulation, and durability for applications such as marine, wind energy, transportation, and industrial components.

Is Divinycell PET recyclable and environmentally friendly?

Yes. Divinycell PET is produced using post-consumer and post-industry recycled PET materials. The thermoplastic structure supports recycling and helps reduce carbon footprint while enabling lightweight composite designs that improve overall sustainability.

Which manufacturing methods work with Divinycell PET?

Divinycell PET foam cores are compatible with most common composite manufacturing processes, including RTM, infusion, and other closed-moulding techniques. The material also performs well in elevated-temperature processing such as prepreg manufacturing.

What are the main advantages of PET foam core materials?

Key benefits include high strength-to-weight performance, low resin uptake, good temperature resistance, and inherent insulation properties. Higher density grades offer strong screw retention and can replace wood in certain structural applications.
