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.
Products
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 (450)
The latest addition to the BiomeHT range. BiomeHTX (450) is a biodegradable and compostable polymer grade. 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 a Heat Deflection Temperature (HDT) of 85°C/185°F without the need for in-mould or post-mould treatment.
Temperature resistance
Our biopolymers show unrivalled heat resistance.
VICAT (A) measures the temperature at which the surface of a test sample starts to soften significantly. Vicat-A Test method ISO306.

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
- Low shrinkage rate (0-0.5%) compared to conventional polymers
- Recycability: waste can be recycled and used with virgin material
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 BiomeHT range has a bio-based carbon content greater than 50%.
- These products are certified 100% biodegradable and compostable according to EN 13432 and ASTM D6400 standards.
