Chemical Testing – Plastic & Resins

What We Test

Comprehensive Evaluation Parameters.

Tests are grouped by type. Under each test you can see which products it is run on, so you can check it fits your sample before sending it in.

Heavy Metals & Toxic Substances

Measures dialkyl tin, cadmium, lead and mercury content using ICP-OES.

Dialkyl Tin C4 & higher homologues, measured as Tin

Measures dialkyl tin compounds (C4 and higher), reported as tin.

Cadmium (Cd)

Measures the cadmium content.

Lead (Pb)

Measures the lead content.

Mercury (Hg)

Measures the mercury content.

Migration & Water Quality

Checks what passes from the material into water, and whether it affects water meant for human consumption.

Effect on Water – Dialkyl Tin

Measures dialkyl tin that has passed into water in contact with the material.

Effect on Water – Cadmium

Measures cadmium that has passed into water in contact with the material.

Effect on Water – Lead

Measures lead that has passed into water in contact with the material.

Effect on Water – Mercury

Measures mercury that has passed into water in contact with the material.

Effect on Water – Other Toxic Substances

Checks for other toxic substances that pass into water in contact with the material.

Overall Migration – Simulant A

Measures the total amount of material that migrates into food simulant A.

Influence on Water Intended for Human Consumption

Checks that the material does not change the quality of drinking water it is in contact with.

Chemical Resistance

Checks how the material resists specific chemicals.

Resistance to Sulphuric Acid

Checks the material after exposure to sulphuric acid.

Resistance to Dichloromethane

Checks the material after exposure to dichloromethane.

Monomer Analysis

Measures residual monomer left in the polymer.

Applies to: PVC resin & compounds

Vinyl Chloride Monomer (VCM) Content

Measures residual vinyl chloride monomer using headspace gas chromatography.

Applies to: PVC resin & compounds

Carbon Black

Measures the carbon black in the compound and how evenly it is dispersed.

Toluene Extract of Carbon Black

Measures the matter extracted from carbon black with toluene.

Volatile Matter of Carbon Black

Measures the volatile matter lost from carbon black on heating.

Carbon Black Content (CBC)

Measures the percentage of carbon black in the compound.

Carbon Black Dispersion (CBD)

Examines under a microscope how evenly the carbon black is dispersed.

Loading of Carbon Black

Measures the amount of carbon black loaded into the compound.

Ash

Measures the residue left after the organic material is burned off.

Applies to: Thermoplastics, HDPE/PP woven sacks

Ash Content

Burns off the organic material in a muffle furnace and weighs the residue.

Applies to: Thermoplastics, HDPE/PP woven sacks

PE Granules

Checks volatile content, sulphated ash and water content of polyethylene granules.

Applies to: PE granules

Volatile Content

Measures the weight lost on heating.

Applies to: PE granules

Sulphated Ash Content

Measures the residue left after burning with sulphuric acid.

Applies to: PE granules

Water Content

Measures the water present in the granules.

Applies to: PE granules

CPVC

Measures chlorine content and sulphated ash in CPVC.

Applies to: CPVC

Chlorine Content

Measures the chlorine content by potentiometric titration.

Applies to: CPVC

Sulphated Ash Content

Measures the residue left after burning with sulphuric acid.

Applies to: CPVC

Polymer Characterization

Measures a property of the polymer that reflects its molecular weight.

Applies to: PVC resin & compounds

K-Value

Measures the K-value, which indicates the molecular weight of PVC resin and compounds.

Applies to: PVC resin & compounds

Polymer Additives

Measures the additive content in the polymer.

Titanium Dioxide Content

Measures the titanium dioxide content using UV-Vis spectrophotometry.

Anti-oxidant

Measures the anti-oxidant content in the polymer.

Oxidation Stability

Measures how well the material resists oxidation at elevated temperature.

Applies to: PE pipes

Oxidation Induction Time (OIT)

Finds how long the material resists oxidation under heat, measured by DSC.

Applies to: PE pipes
