Available sizings & packaging
Available sizings :
- QS1318 and QS13-QPC1 are multipurpose high performance direct sizings, recommended for most textile processes and composite applications. They can be used with thermoset resins and among others : Phenolic, Epoxy, BMI, etc..
- QSCY1 sizing is designed specifically for optimized compatibility with cyanate ester resin systems.
*Sizing is the chemical agent which aims at protecting the yarns in textile processes as well as providing chemical compatibility with resin matrix in composites.
Type of packaging:
All Quartzel yarns are packed onto H3 bobbins. See the graph beside.
