Plastic, composite and elastomer testing solutions

The plastics industry has emerged as a powerhouse, covering traditional plastics, advanced composites, and highly stretchable elastomers. These materials offer exceptional versatility and, at times, astonishing levels of elongation.

With the capability to handle even extreme levels of stretching, our universal testing machines stand tall, providing the extra reach needed for comprehensive testing.

In rigid materials, precision is essential, similar to the metal industry. Bending tests are also a common practice in the plastic industry, highlighting the need for versatile testing solutions. Explore our specialized universal testing machines designed for plastics, composites, and elastomers.

In line with custom or global standards

At Barrus, we offer a diverse range of testing solutions for plastics that can be tailored to your specific needs or aligned with international standards.

ISO 527, a fundamental standard for tensile testing and elongation measurement, holds significant importance in our testing processes. Our services cover a wide spectrum, from plastic films conforming to ISO 527-3, to injection and extrusion molded plastics complying with ISO 527-2, and flexural properties evaluations in accordance with ISO 178.

We prioritize strict adherence to recognized international standards, including EN, ISO, ASTM, and DIN, for comprehensive mechanical testing.

For those seeking non-standardized testing, our customized solutions are readily available upon request, ensuring your unique testing requirements are addressed.

Melt Flow Indexers (MFI)

Melt Flow Indexers (MFIs) are crucial tools used in manufacturing, especially in processes like injection molding that involve resins. Analyzing flowability is essential in plastic material testing, measuring the viscosity of heat-softening polymers at specific temperatures. MFIs assess material flowability, ensuring the material reaches even intricate mold sections.

The Barrus Flow family offers cost-effective, highly precise solutions for plastic material flow index determination, covering both MFI/MFR and MVI/MVR measurements.

These instruments meet or exceed international standards such as EN ISO 1133, ASTM D1238, and GB/T 3682 A & B methods, providing highly accurate results. With a wide measurement range of 0.1 to 100g/10 minutes for MFI/MFR and 1 to 150 cm³/10 minutes for MVI/MVR, they accommodate various plastic materials.

The MFIs feature efficient automatic cutting with adjustable timing accurate to 0.01 seconds and precise temperature control within ≤0.2℃, ensuring consistent and reliable results. Their user-friendly interface, equipped with a large, colorful touchscreen, simplifies operation, making plastic material testing straightforward and efficient.
