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  offer a higher temperature stability whilst being 100% biodegradable and compostable.
Biome is continually developing this range of heat stable products. The latest addition to the HT family is BiomeHTX: a fibre-reinforced grade, designed specifically to produce stiff and strong injection-moulded parts.




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 (450)

This is the latest addition to the BiomeHT range. BiomeHTX (450) is a biodegradable and compostable polymer grade. Compostable being industrially compostable with a potential to certify to 3.2mm (according to ASTM D6400 and EN13432 standards, certified thickness will be dependant on geometry of application). This reinforced polymer made from a blend of renewable plant   feedstocks produces strong, rigid parts. Offers HDT of 85°C/185°F without the need for in-mould or post-mould treatment.

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.
