Capabilities
At Trostel, everything we do is designed to deliver a superior product to customers who demand rapid response, optimal dispersion and customized solutions.
Quoting
Trostel prides itself on rapid response to RFQ’s. We realize that to compete in today’s global environment, our customers often need quotations processed within 24 hours. Depending on the complexity of the application, quotes can be processed the same day.
Samples
Trostel has a Shaw K1 intermeshing mixer that produces 8-12 pound sample batches. Once a formulation has been quoted/agreed upon, a sample can be produced within 24-48 hours.
Quality Control
Trostel has a fully equipped Quality Control (QC) laboratory, ready and able to test compounds to the most demanding of specification requirements.
Production
K-5 (143 Liter) and K-1 (3.5 Liter) Intermix® brand mixers.
Intermixes® use intermeshing rotor technology now so popular with new, modern rubber mixing plants. The entire weigh-up, mixing and packaging operations are controlled using Mesabi® computer systems. This provides material traceability throughout the process. Material after mix, pass through two mills and are cooled and packaged on a VMI® batch-off.
Four (4) indoor carbon black storage silos.
Materials are unloaded from bulk trucks in an indoor truck bay. This insures that the black is dry and not at near freezing temperatures during the winter nor at three digit high temperatures during the summer. The entire facility is air conditioned. Bulk Super-Sak stations for dry powders and movable totes for bulk oil are also available. Customers have the option of receiving their materials as strips, slabs or prep stocked.
Three (3) prep machines
- 2 Zwik ZW® continuous preformers (one for polar, one for non-polar polymers)
- 1 Barwell® preformer.
All three systems utilize Infinity QS software for statistical weight control. Trostel routinely holds ± 5% prep weight with a Cpk greater than 1.60.
Testing
Our Lake Geneva Wisconsin Laboratory performs a variety of standard rubber tests including, compression set, tension set, along with a available a wide variety of ASTM* performance tests and analytical procedures in the Lake Geneva Wisconsin Laboratory.
Lab equipment
- Alpha Technology® MDR and RPA rheological test machines
- Alpha Technology® T-2000 Tensometer Picture of the PCD Lab
- Zwick® digital durometer and densometer
- Dispergrator® dispersion analyzer
Tests performed include but are not limited to:
- FT-IR, Fourier Transform Infrared
- The preferred method of infrared spectroscopy DSC (TG & peroxide state of cure)
- Differential Scanning Calorimetry or DSC
- A thermo analytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference are measured as a function of temperature.
