What is the R&D value of PET/PP spinning? The answer may not lie in the laboratory, but in the end-application fields of seven major industries. HALU’s laboratory twin-screw melt spinning machine is helping customers in various industries quickly transform new material formulations into evaluable fiber samples.
Packaging Industry:
Biodegradable PBAT/PLA flat and monofilament yarns for woven bags, tea bag yarn, and heat-sealable packaging materials. Customers are using the equipment to quickly verify the effectiveness of anti-hydrolysis agents and opening agents, successfully solving crystal point and brittleness issues.
Agriculture:
Spinability verification for anti-aging drip irrigation tape and agricultural greenhouse film functional masterbatches. Customers have developed experimental-grade agricultural yarns with a 30% improvement in UV aging life, shortening the formulation iteration cycle from six months to one month.
Industrial Applications:
Formulation development for automotive lightweight reinforced plastics and industrial filter screen monofilaments. The side-feed design effectively maintains the aspect ratio of glass fiber, allowing pilot-scale data to directly guide process settings for large-scale production lines.
Food-grade materials:
Low-odor TPE elastomers and food-grade contact materials. The equipment is equipped with a dual vacuum exhaust system to achieve deep devolatilization, ensuring low residue and low leaching of samples, passing food-grade testing on the first attempt.
Tobacco industry:
Spinning simulation of cellulose diacetate tows. Precision metering pumps and specialized spinning components accurately control tow denier, uniformity, and flavoring agent ratio, completely replicating the tow forming effect of an actual production line.
Medical applications:
Micro-scale research and development of absorbable bio-sutures (PGA/PCL) and cardiovascular stent braided monofilaments, meeting high cleanliness standards. Samples can be directly used for pre-implantation evaluation.
Specialty materials:
Covering spinning and forming research of various high-value-added materials such as PP/PE blends and specialty engineering plastics.
