Tittle:
Biodegradable materials with improved thermal resistance and acoustic insulation properties
Summary:
A Spanish technological centre expert in polymeric materials processing offers their know-how in the development of bio-fibres with improved thermal properties to produce 3D-fibre formed parts that can be applied in acoustic and thermal insulation. They look for partners for a technical and/or research cooperation agreement, to adapt the materials to specific requirements and/or develop new materials for new applications.
Description:
Currently in all industrial sectors there is an increasing focus on environmental impact, particularly at the end of service life. With this aim, most of the companies look for alternatives to traditional plastic components. Among them, it is highlighted the automotive industry that looks for an alternative to plastic textile components.

Researchers focus on the development of textiles from fibres made of polylactic acid (PLA) derivatives as a substitute for the conventional polyester fibres. PLA is a biodegradable thermoplastic polymer that comes from renewable sources such as corn starch or sugar cane.

The main limitation of conventional PLA is the thermal resistance: PLA softens at a temperature around 52ºC, which limits its use in applications that require temperature resistance at pressure and conditions of environmental and chemical stress.

A Spanish Technological Centre with broad experience in polymeric materials processing and involved in many R-Y-D projects related to modification of polymer properties, has developed a compound from PLA fibers that is able to fulfil the requirements for automotive interior applications, including aspects such as thermal resistance, fogging, odour emissions, VOCs and antimicrobial resistance.

The PLA blend formulation and the processing conditions are key factors that determine the performance of the materials. It has been proved as possible to increase the softening temperature from 52ºC to 102ºC, without compromising the viscosity of the material, which can then be processed by extrusion melt spinning in order to obtain the fibers.

These fibers can be successfully converted into fabrics and non-woven samples in order to obtain a final prototype of a moulded door panel. Two non-woven layers and a woven fabric are combined into a composite consisting of 100% bio-based material (See attached picture).

These results were obtained in the framework of the BIOFIBROCAR project, funded by the 7th European Framework Programme, in which the centre explored the feasibility of substituting the polyester and polypropylene (PP) fibres then applied in car interiors, by PLA-based fibres.

The centre offers the know-how in the development of fibres with improved thermal properties in order to combine it with new technologies producing 3D-fibre formed parts to be applied in acoustic and thermal insulation.

They are interested in collaborations with users of these acoustic and thermal insulations in any sector, through a technical cooperation agreement, in which the centre can adapt the materials to the specific requirements of the application.

On the other hand they would also like to be contacted by potential partners interested in a joined development of new materials for new applications, through a research cooperation agreement.
Advantages and Innovations:
- The material is environmentally friendly, as it is biodegradable.
- The softening temperature of the material has been increased from 57ºC to 102ºC without affecting the viscosity of the material, so it can then be processed by extrusion melt spinning in order to obtain fibers.
- The material can be processed by standard equipment of extrusion.

Partner sought

Type and Role of Partner Sought:
The centre would like to collaborate with users (companies, technology centres or universities) from any sector that requires acoustic and thermal insulations. The partner may indicate the specific needs of the application and the Spanish centre will adapt the materials for an appropriate use. A technical cooperation agreement will be established.

On the other hand the centre would also like to be contacted by potential partners (companies, technology centres or universities) that need the developed know-how to obtain new materials to be used in different applications. A research cooperation agreement will be established.
