Plan a trial for your application
Rigid PVC profiles
In the same base formulation, compare low-temperature notched impact, fusion and appearance.
Impact modification of extruded pipes and fittings
Record extrusion pressure and dimensional stability, and perform the target impact test.
Purchase specifications and incoming inspection
Review these properties for the intended application grade. Example figures refer to the cited grade or source. Confirm the offered specification, packaging and lead time in the quotation. Resonac ELASLEN CX · Chlorinated polyethylene grades ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Chlorine content | % by mass | Confirm against the offered grade and purchase specification | Report on an as-received basis for the corresponding grade. |
| Volatiles | % by mass | Confirm against the offered grade and purchase specification | Use the same drying temperature and time. |
| Impact strength retention | kJ/m² or method-specific | Confirm against the offered grade and purchase specification | Keep formulation, specimen thickness, notch and test temperature constant. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
For powder or granules, specify modification purpose, bulk density and net weight. Do not substitute cable-grade data.
Storage and handling
Check lot and fusion curve. Record moisture exposure and agglomeration separately.
Sample and order lead times
State the finished part, machine trial quantity and routine order size. Match trial and commercial grades and agree MOQ, load unit, lead-time start and arrival.
Questions from the plant
Does higher chlorine content necessarily improve impact resistance?
Compare impact, fusion and other required properties in the plant formulation at its relevant low temperature.
Can CPE replace ACR at equal addition?
Distinguish impact modification from processing assistance, then validate the part and process separately.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check Chlorine content, Volatiles, Impact strength retention.
