Bio-resins traditionally show poor mechanical properties at higher temperatures and often come under pressure from being food-source derived. The BiomeHT range offers unrivalled heat resistance whilst retaining impressive environmental credentials. The HT family of products consists of cellulose-based high temperature grades made from a GM-free, non-food derived source and offers a higher temperature stability whilst being 100% biodegradable and compostable.
The latest addition to the HT family is BiomeHTX: a fibre-reinforced grade, designed specifically to produce stiff and strong injection-moulded parts.

Products

BiomeHTC

Our BiomeHT range offers a higher temperature stability whilst retaining outstanding environmental credentials. With excellent room temperature mechanical properties, BiomeHTC has a softening point of 70°C in both dry and aqueous conditions. It also offers greater transparency and is perfect for clearer products.

BiomeHT70

BiomeHT70 is suitable for applications where temperatures may reach 70°C, which may occur in the logistics chain. BiomeHT70 has a softening point of 90°C whilst still maintaining good flow characteristics.

BiomeHT80

BiomeHT80 is suitable for applications where temperatures may reach 80°C, for example electronic applications.

BiomeHT90

When temperature resistance is paramount, BiomeHT90 is the answer. With a softening point of 110°C, some 40–50°C higher than competitive bioplastics, BiomeHT90 is the perfect choice for food service and electronics applications.

BiomeHT90 - Injection

The perfect solution for high temperature resistant, injection moulded products.

BiomeHT90 - Extrusion

The right choice for high temperature resistant sheet extrusion and thermoforming applications. Proven to be stiffer than oil-based PS, allowing the convertor to down gauge without affecting mechanical properties or functionality.

BiomeHTX

The latest addition to the BiomeHT family. 100% bio-based, offering outstanding temperature performance (>130°C/>266°F) following a short post-moulding heat treatment.

properties_50

Key properties




  • BiomeHTC, HT70, HT80 and HT90 are made from a non-food derived, GM-free source

  • New BiomeHTX is derived from plant starches, free from GMOs

  • Rigid materials with softening point up to 130°C (266°F), ~70°C higher than other standard bio-materials

  • Suitable for injection moulding as well as sheet extrusion and thermoforming

  • Compostable, with a bio-based carbon content greater than 50%

  • Suitable for food service products, hot beverages, cosmetics, electrical and other heat sensitive applications

  • EU and FDA food contact approved



processing_50

Processing




  • Processes well on conventional injection moulding machines (hot and cold runner systems)

  • Can be injection moulded with characteristics similar to ABS

  • Comparable cycle times can be achieved compared to conventional polymers

  • Typically stiffer than oil-based PS, allowing significant scope for down-gauging (extruded sheet) without compromising mechanical properties or functionality

  • Low shrinkage rate (0-0.5%) compared to conventional polymers

  • Recycability: waste (typically up to 50%) can be recycled and used with virgin material



sustainability_50

Sustainability


 


We aim for the highest possible bio-based content in all of our products and are continually developing our range to improve sustainability.


Currently our cellulose-based BiomeHT range has a bio-based carbon content greater than 50%.

BiomeHTX has a bio-based carbon content of 100%, as measured to ASTM D6866-16.

These products are certified 100% biodegradable and compostable according to EN 13432, ASTM D6400 and Vincotte OK compost.
