Measure density - eliminate defects before your customer finds them.
The density of plastic is not just a number-it’s a crucial indicator of your raw material quality. Even slight variations can point to significant issues, such as:
- presence of unwanted additives or fillers (e.g., chalk, talc),
- excessive moisture content,
- incorrect production parameters,
- batch-to-batch instability, even in virgin (prime) materials.
Which plastics can you measure with the RBDT-1 Density Tester?
The RBDT-1 Density Tester provides fast, precise, and repeatable density measurements for a wide range of thermoplastic materials, including both virgin (petrochemical-based) granulates and recycled materials (regranulates, regrind):
Polyolefins:
- PE (HDPE, LDPE, LLDPE, MDPE, UHMWPE)
- PP (homopolymers, block copolymers, random copolymers)
Styrenics:
- PS (GPPS – general-purpose polystyrene; HIPS – high-impact polystyrene)
- ABS (acrylonitrile-butadiene-styrene)
- SAN (styrene-acrylonitrile)
- ASA (acrylonitrile-styrene-acrylate)
Engineering and Technical Plastics:
- PVC (polyvinyl chloride – rigid and flexible)
- PET (virgin and recycled RPET)
- PA (PA6, PA66, PA12 polyamides)
- PC (polycarbonate)
- POM (polyoxymethylene, polyacetal)
- PMMA (acrylic, polymethyl methacrylate)
High-temperature and Specialty Plastics:
- PEEK (polyetheretherketone)
- PPS (polyphenylene sulfide)
- PSU (polysulfone)
- PEI (polyetherimide)
- PVDF (polyvinylidene fluoride)
Thermoplastic Elastomers (TPE):
- TPU (thermoplastic polyurethane)
- TPO (thermoplastic olefin elastomers)
- TPV (thermoplastic vulcanizates)
Why is density testing important even for virgin (prime) raw materials?
Even prime (virgin) raw materials can exhibit subtle variations between batches due to:
- minimal fluctuations in petrochemical production processes,
- changes in molecular weight distribution, subtly affecting the plastic properties,
- unseen contamination or alterations in additives, pigments, or stabilizers.
Regular density testing helps detect these subtle differences, resulting in improved production stability, fewer customer complaints, and enhanced market reputation.
