 Manufactures go to Associated Polymer Labs to have a performance evaluation done on their products because they want to be assured their product performs. Many companies can’t afford to have a product failure, defect, or worse a recall.   

Long term creep tests are performed either in tensile or compression mode.  Data from creep and creep-rupture tests are necessary to predict the creep modulus and strength of material under long term loads.  It is also used to predict dimensional changes that may occur as a result of such loads

TGA is commonly employed in research and testing to determine characteristics of polymer and plastic materials to determine degradation temperatures, absorbed moisture content of materials, the level of inorganic, organic components, additives, decomposition points and solvent residues. TGA determines the change in weight relation to change in temperat

Dynamic Mechanical Analysis is a proven effective tool in characterizing open cell foams like polyurethanes, and closed cell polyolefin foams.

Melt Rheology Testing provides a quick, efficient, accurate, and cost effective means for detecting potential problems in the processing of polyolefin resins, co-polymers, blends, and rheology modifiers. Plastic melt rheology eliminates the need for time consuming melt tension measurements and inadequate melt index measurements. Detect processing problems of polyolefins before large quantities of off spec product are produced. Before you take your product to the assembly line, make sure you have the rheology data to avoid costly recalls and scrap.

One of the first fundamental steps in new product development is feasibility. When studying the products' feasibility, it is necessary to study material compatibility and review the selection of materials. Most medical devices contain many parts or components that are integrated together.

A great test package, for incoming raw material resins, and to determine the viscosity as a function of temperature. In order to successfully predict the processibility of polymer melts, it is important to characterize the viscoelastic properties and the temperature dependency.

Stress sweeps, also referred to as amplitude sweeps, are used as an efficient way to characterize material stability. The wider the linear viscoelastic range the more stable the material.

Fourier Transform Infrared Spectroscopy (FTIR) identifies chemical bonds in a molecule by producing an infrared absorbtion spectrum.  The FTIR generate an infrared spectral scan of samples that absorb infrared light.  Metals do not absorb infrared light, but polymers that contain metals can be scanned with FTIR.

Get your products to the market faster, with APL’s innovative foam trial evaluation.  Cut down your resin waste costs.  Now you can screen your material ahead of time and reduce the trial period and associated costs from the current industry standard  of several months, down to

DMA is probably the most versatile thermal analysis method available, and no other single test method provides more information about a sample in a single test.  Besides material properties, DMA provides a direct link between a material's chemical makeup and its' mechanical behavior.  Materials can be characterized by DMA regardless of their kind, their physical state or the form in whi

DMA is short for Dynamic Mechanical Thermal Analysis (DMTA), which is another name for Dynamic Mechanical Rheological Testing (DMRT).

Rheometers for mechanical rheometry are of two types:

1)Linear displacement, RSA II Rheometrics Solids Analyzer

2)Rotational, SR5 Rheometrics Controlled Stress Rheometer

Rheology is the science that studies the deformation and flow of materials, whether in liquid, gel, melt, solid, or composite form, in terms or their elasticity and viscosity.

Dynamic Mechanical Analysis      DMA

The DMA determines changes in sample properties resulting from changes in five experimental variables: temperature, time, frequency, force, and strain. The deformation can be applied sinusoidally, in a constant, or under a fixed rate. The DMA uses samples that can be in bulk solid, film, fiber, gel, or viscous liquid form. Interchangeable fixtures are employed to allow you to measure many properties, including: modulus, damping, creep, stress relaxation, glass transitions, and softening points.
