Physico-chemical and Rheological Tests

• the resistance,
• the texture,
• the performance,

of products, based on their normal or reasonably foreseeable intended use.

They can be divided in

• "test to appraise the resistance", e.g. resistance to
  • traction,
  • tearing,
  • compression
  • perforation
  • fracture
  • abrasion
  • impact and dropping
  • leakage

• Performance:
  
  • Absorption of liquids and the comfort of diapers, incontinence products, sanitary towels, and pantyliners. We offer a comprehensive range of assessments for these products, including rewetting, absorption speed, absorption capacity in accordance with ISO 11948-1, run-off, the performance of fastening tabs, re-fastenability, etc.
  • Ability to pick up and trap suspended solids (dust)
  • Adherence to surfaces
  • Static and dynamic coefficient of friction
  • Performance of shopping bags, waste bags, freezer bags
• Texture:
  
  • Viscosity
  • Firmness
  • Spreadability

The tests can be carried out to evaluate a specific aspect of a product, to compare the data obtained with a technical specification or with the performance of rival products, and/or to evaluate the product after accelerated aging (link). Our laboratory is able to evaluate the physico-mechanical characteristics of a wide range of materials, including plastic films, paper, textiles, non-woven fabrics, and gloves, using both standard and internal methods, developed to meet specific customer demands.
