| Ingeo 8052D – a product from NatureWorks LLC – can be converted into an expanded foam sheet with use temperatures up to 77°F (25°C). This foam is lightweight, strong and suitable for packaging fresh meat and vegetables. In order to extrude foam with the desired expansion properties, this grade must be modified with a branching agent such as Joncryl® 4368C.&& |
