ESCR h 3 SABTEC Method

Application
LTH 1922 is specially developed for applications that require a good balance between flow
properties and mechanical properties, e.g. toys, household articles, clamping lids.
General information
LTH 1922 has been manufactured using SABTEC licensed technology.
Packaging
Supplied in pellet form and can be packaged in 25kg bags, 1 ton semi bulk or 17 ton bulk.
Food packaging
The above mentioned grade meets the relevant requirements of plastics directive 2002/72/EC
(06-08-2002) and its amendments till directive 2008/39EC relating to plastic materials and
articles intended to come into contact with foodstuffs .

Pharmaceutical Application
The above mentioned grade meets the requirements of the European pharmacopeia version 6
section 3.1.5 for pharmaceutical application.
Conveying
Conveying equipment should be designed prevent accumulation of fines and dust particles can,
under certain conditions, pose an explosion hazard. We recommend that the conveying system
used:
1. be equipped with adequate filters
2. is operated and maintained in such a manner to ensure no leaks develop
3. that adequate grounding exists at all times
We further recommended that good housekeeping will practiced throughout the facility
Storage
As ultraviolet light may cause a change in the material, all resins should be protected from
direct sunlight and/or heat during storage. The storage location should also be dry, dust Free
and the ambient temperature should not exceed 50 0C. It is also advisable to process
polyethylene resins (in pelletized or powder from) within 6 months after delivery, this because
also excessive aging of polyethylene can lead to a deterioration in quality.
Handling
Minimal protection to prevent possible mechanical or thermal injury to the eyes. Fabrication
areas should be ventilated to carry away fumes or vapors
