Our 100% biodegradable product line consists of PLA, PBS, PBAT, TPS and blends of these polymers reinforced with natural fillers. Materials are given various mechanical, thermal and visual properties, using a range of bio-fillers such as natural fibres, agricultural and consumer food waste.
These materials require specialist compounding due to their low thermal stability and are pre-treated before compounding. Thanks to its know-how in engineering plastics formulation and processing, 4PLAS LTD offers customized sustainable bioplastics by producing materials that allow for a wider range of use and deliver better performance to meet challenging technical requirements
4ETEC® compounds offer the following key properties:
- Natural and environmentally sustainable
- Low carbon footprint
- Low Waste
- Balanced mechanical properties
- Efficient use of resources
- Wide range of cosmetic finishes
- Extensive range of performance enhancing additives and fillers
4ETEC® offers the following range of products:
- Custom colours
- Impact modified

4ETEC® grades are supplied in pellet form and packed in moisture proof 25kg bags. Other forms of packaging such as octabins and big-bags are also available.
4ETEC® biodegradable materials need to be pre-dried in hot air drier systems and should be processed as soon as possible after drying.
It is highly recommended to check the actual moisture content before processing.
4ETEC® compounds can be processed on all commercial injection moulding machinery.
It is necessary to have precise temperature control for processing Biopolymers to avoid thermal degradation and overheating.
4ETEC®with natural filler and fibres are highly sensitive to heat and they should be processed gently, maintaining low processing temperature. Low injection pressures speed and residence time will provide better performance.
For more information on this product, see our processing guides, troubleshooting guides and chemical resistance charts.
Recycling requires special caution in order to prevent contamination during the various grinding phases. Regrind should be free of contamination, should not be thermally degraded and must be dry as moulded, or be dried prior to reuse.
The ratio of recycled material should be adjusted on the basis of the mechanical and other properties of the end component, but generally should not exceed 30% by weight.
Under normal conditions 4ETEC® is not a toxic or hazardous material. During processing preventative action should be taken to avoid direct contact with the polymer melt or inhalation of any gases produced. Processing temperatures above 300°C should be avoided. Detailed safety information can be found in our material safety data sheets (MSDS).
