Norner has unique competence in the main application areas and businesses of plastics. This has been developed during the four decades of R&D labs in Norway. Each processing method and application area has a unique range of test methodology which is described in more detail in the below paragraphs.
Barrier calculations can be carried out on different geometries; film, cup, bottle and cuboid. This enables you to simulate your target package design. The calculating models gives you estimates of the O2 (oxygen), Water Vapour and CO2 Transmission Rate of various plastics packaging material like PP, PE, PET, PA and EVOH.
These barrier properties of coextruded, co-injection multilayer and in-mould-label solutions can be studied and evaluated by adding layers of the geometry or IML.
The combination of geometrical options, permeability properties and environmental conditions provides a useful tool for design and development.
You can now add a sequence of conditions as you experience in the logistic chain with different temperatures and humidity.
Define packaging type and geometry parameters (e.g length, radius, height, width)
There are numerus polymeric and plastic products used in any building. This range from products like plastic membranes, surface coatings, insulation and electrical to water supply and plumbing. All of these applications require durability and specific properties for their use. We test and support the producers and the building industry with a wide range of relevant testing:
Norner helps protecting the homes of our customers, reducing failures and saving costs.
We offer a specified test scheme for pre-qualification of pipe conduits for pipe-in-pipe systems.
When installing water distribution in domestic houses and apartments, the PEX supply pipe will be covered by a corrugated pipe, often called a Pipe in Pipe system.
The inner pipe is a PEX plastic pipe with very stringent regulations. The outer corrugated sleeve has a security function of leading away potential leaking water, if the PEX pipe gets a rupture. These tubes had no regulations until recently, and due to quality variations and problems of the tubes it has resulted in cracking tubes and several insurance claims.
A new test scheme, Sintef Byggforsk “Test method for pipe in pipe systems, for approval", has been implemented in Norway and includes the analysis of several quality parameters:
Pigment dispersion and homogeneity
Raw material quality vs. gels
Thickness distribution of the profile
Presence of notches in the tube profile
Norner offers pre-qualification according to the above mentioned tests of the pipe-in-pipe systems. Qualified systems have to be sent to Sintef Byggforsk to obtain a Sintef technical approval.
