LDPE 780E Low Density Polyethylene Resin can be readily processed using conventional injection moulding techniques utilising melt temperatures between 140 and 250°C, a mould temperature between 10 and 50°C, and injection pressure between 50 and 150 MPa.
When properly injection moulded, 780E Low Density Polyethylene Resin exhibit:
Excellent flow
Good rigidity
Good surface gloss
Note: LDPE 780E Low Density Polyethylene Resin should comply with FDA regulation 177.1520 and with most European food contact regulations when used unmodified and processed according to good manufacturing practices for contact applications. Please, contact your nearest Dow office for food contact compliance statements.The purchaser remains responsible for determining whether the use complies with all relevant regulations.
Applications:
Housewares.
Toys & leisures.
Containers.
Compounding.
Complies with Canadian HPFB No Objection
Complies with U.S. FDA 21 CFR 177.1520
