Rondo and the Polykemi group consider that in order to fulfil our basic principle of giving our customers high quality compounds, we must have a well developed laboratory.
Our laboratory can currently perform a large number of different tests to ensure that compounds we sell to our customers have the properties they require.
Our laboratory operations are based on well trained employees with specialist knowledge within polymers, additives and pigments, who have access to a large range of special instruments for testing/inspection of plastic raw material.
The flexural and tensile properties of the material are tested by applying a load to test specimens for a given time period. Such testing provides values such as E-module, flexural stress, tensile stress and elongation.

We use a spectrophotometer to ensure accurate color measurement of all colors. We monitor colors in D65, A, TL84 light and the color measurement equipment measures according to the dE, dL, dA, dB, dC, dH equation.
Testing equipment: MacBeth Ci5 and Macbeth 310
A glow wire is heated up to different temperatures (between 650 – 960° C) and a test specimen is applied to the glow wire. This test method is frequently used in the electronics industry.
Testing equipment: Friborg GWT
This testing equipment checks the rate at which a material burns (mm/min) and the test method is designed for the automotive industry.
Testing equipment: Atlas HMVUL
Materials are tested for flammability to meet the UL-94 standard. The materials are classified into UL-94 flammability classes V0, V1, V2, HB and 5VA and 5VB.
Testing equipment: Atlas HVUL2 horizontal vertical flame chamber
The MFI measurement method is the most common way of testing a material’s flowability.
Tests are performed at predetermined temperatures and weights.
Test equipment: Zwick 4106.
Gas chromatography is able to quantify the contents of a plastic material.
Testing equipment: Perkin Elmer Clarus 500
This instrument is the latest technology for analyzing the scratch-resistance of a material. It makes scratches in a grid pattern which is then measured in the spectrophotometer.
Testing equipment: Erichsen Scratch tester 430P
Measurement of impact strength, performed with both cutting and non-cutting test sticks.
Testing can be performed at room temperature (+23°C) and at temperatures down to -40°C.
Test equipment: Ceast Resil 5.5
With our XRF equipment, we can verify that our recycled raw material does not contain any heavy metals. We can thus comply with the RoHS Directive (2011/65 / EC).
We can analyze both the occurrence and how much of the following heavy metals contained in a raw Mercury (Hg), Cadmium (Cd), lead (Pb), Hexavalent Chromium (Cr6 +), Polybrominated biphenyls (PBB) and Polybrominated diphenyl ethers (PBDEs).
Test specimens/end components are exposed to UV light, heat, humidity and rain simulation. Testing provides the best possible simulation of how the plastic changes (color, mechanical properties etc.) when placed outdoors in different environments.
Testing equipment: Atlas Suntest XXL
