Description

Kimya HIPS-R is a 3D printing filament made from recycled High Impact Polystyrene (HIPS), part of the styrenic polymer family. Despite being made from recycled materials, HIPS-R maintains strong impact and heat resistance, making it a reliable and sustainable option for various applications. Its low permeability makes it well-suited for leak-proof containers, while its solubility in D-limonene sets it apart from other filaments - allowing it to be used as a dissolvable support material. Kimya HIPS-R is commonly used in packaging, household appliances, and dual-extrusion printing setups.

Benefits

• Dissolvable.

• Durable.

• Sustainable Choice.
