RavaRoto 1490

RavaRoto 1490 Natural Powder is a hexene linear low-density polyethylene for rotational moulding based on
Lupolen 3712 F RM.

Typical customer applications include rotational moulded parts with good stiffness and toughness.

RavaRoto 1490 Natural Powder is fully heat and UV stabilised resulting in good processing latitude, good colour
retention and long life expectancy.

This grade is a very fast processing material but also has extremely high levels of ESCR and a very wide processing
window for -40C ARM impact strength. Recommended PIAT can be as low as 130C to 150C depending on the
position of the thermocouple. It is suitable for use in many different applications due to its high ESCR. But it is
especially good for reducing oven cycle time by up to 30%. This is done using low PIATs and can result in
significantly lower energy usage heating the oven. This effect is multiplied in thicker wall section. It is easy to
process with a low shrinkage tendency. Faster melting can help to distribute the material more evenly across the
mould.

This material is not intended for use in medical- and pharmaceutical applications.
