Experimental Data
- Measurement time : Depending on the type and characteristics of the resin, it usually takes 1 to 2 weeks - Preparation for measurement request : If you are requesting measurement of physical properties, please prepare as below. 1) Polymer sample (at least 1 kg is required to measure all items) 2) Polymer type / grade / manufacturer (eg: ABS / XR-401 / LG Chem.)
3) Polymer property table provided by manufacturer
