## Product Texts

PA 1101 is a whitish polyamide 11 powder, which is optimised for the use as a laser sintering material. PA 1101 is made out of renewable raw materials (castor oil). The material is characterised by elasticity and high impact resistance.

## Properties

• high elongation at break  
• elasticity  
• high impact resistance  
• excellent resistance to chemicals, especially hydrocarbons, aldehydes, ketones, mineral bases and salts, alcohols, fuels, detergents, oils and fats

## Acceptance criteria

• cytotoxicity according to DIN EN ISO 10993-5

## Typical applications

• mechanically loaded functional prototypes and series parts with long-term moving elements (e.g. hinges)  
• in the automotive industry, it is mainly used for interior components for crash relevant parts (PA 1101 components do not splinter)  
• especially suited for small to medium sized parts, thin walls and lattice structures
