Lab Capabilities
ResinLab's state of the art laboratory instrumentation has the capability to support all of our customer's needs. Used for both product development and quality control, these instruments allow us to validate design parameters and verify they stay in range with every production lot of material.

TA Instruments 2910 Differential Scanning Calorimeter
Used to characterize the thermal response of products. Exotherm, glass transition points, melting points are among the key properties clearly identified by this instrument.

Thermocouple Data Acquisition
Captures the reaction profile and exotherm of a curing polymer in a defined part. This can be run at various ambient temperatures to show the effect of mass, geometry and surrounding materials on heat generation and dissipation to assure a low stress casting.

MTS QTest 25
A versatile physical tester used to measure a product's tensile strength, elongation, compressive and flexural properties and adhesion to various materials.

Nicolet Nexus 470 FT-IR
Used to identify the chemical fingerprint of polymers.

Brookfield Viscometers

  • DV II + Thermosel Viscometer
  • DV III Ultra Thermosel Viscomete
  • RVT

We also offers an extensive line of electrical and electronic resins including:


ResinLab is RoHS compliant

Custom Packaging
