Polyglykol PE-K 270 S

Hypercompressor lubricant for LDPE production

Edition Date :
November 16, 2021

Polyglykol PE-K 270 S is a high-performance lubricant, especially designed for the use in high pressure production processes of low density polyethylene (LDPE). It is a polyalkylene glycol (EO/PO random copolymer) with an excellent intrinsic lubricity and a high viscosity index, showing a favorable pressure-viscosity relationship.


Polyglykol PE-K 270 S holds all relevant approvals

Pumpability certificate from Burckhardt Compression
The pumpability of the Polyglykol PE-K 270 S has been tested and approved by Burckhardt Compression for cylinder lubrication of secondary compressors equipped with “CH” lubrication pumps in high pressure polyethylene processes for the production of Low Density Polyethylene (LDPE) up to a maximum final process pressure of
• 3900 bar at a minimum oil temperature of 50 °C
• 3500 bar at a minimum oil temperature of 35 °C

• 2370 bar at a minimum oil temperature of 20 °C

Process approval by Lyondell Basell
Lyondell Basell tested and approved the use of Polyglykol PE-K 270 S in ethylene hyper compressors, which operate in plants using Lupotech LDPE technology.

Food grade approval
Polyglykol PE-K 270 S is NSF-H1 listed and registered under no. 149419. It is also compliant with the food regulations of the US (FDA 21 CFR § 178.3570), the European Union (EC Directive 10/2011/EC) and Germany (BfR Recommendations V, VI, XIV, XL VIII, LI, LII, LIII).

Safe use and handling
Polyglykol PE-K 270 S has a favorable eco-tox profile and is free of human and environmental hazard labels according to the CLP/GHS (Globally harmonized system of classification, labeling and packaging of chemical substances and mixtures).

Broad registration status
Polyglykol PE-K 270 S is a polymeric material and therefore REACh-exempted. The monomers have been registered during REACh phase 1.

It is registered in all major chemical inventories, i.e. AICS/Australia, DSL/Canada, ENCS/Japan, IECSC/China, KECI/Korea, PICCS/Philippines and TSCA/USA.
