In recent years, ubiquitous plastic products have made environmental pollution more and more serious.Europe, the United States, and China have successively introduced "plastic restriction orders" to prohibit the production and sale of certain plastic products，promote green plastic products，explore new business forms, standardize the recycling and disposal of plastic waste, and specialize in the treatment of plastic waste.

CTI provides you with professional testing services for biodegradable plastic products. Applicable products include disposable tableware, postal express packaging products, hotel supplies, resin and starch products, and plant fiber molded products.The test methods include a series of standards including GB/T 19277.1-2011, ISO 14855-1:2012,help enterprises to control the quality and safety of materials.

Human activities will produce ozone-depleting substances (ODS), such as chlorofluorocarbons, halons and methyl bromide, which have a significant destructive effect on the ozone layer. ODS is widely used, including the production or use of refrigerators, air conditioners, electronic products, fire-fighting equipment, tobacco, foam plastics, hair gel and pesticides. CTI can provide a complete set of ODS testing for Montreal Protocol, EU ODS regulations and China Controlled Ozone Depleting Substances List.

Mould stress relief is to ensure the thermoplastic shells of medical electrical products, formed through mold pressing or injection molding, are well constructed. Any shrinkage or deformation stemming from internal stress during the process of mold pressing or injection molding cannot lead to any unacceptable risks. The Mould stress relief  test, which evaluates the safety characteristics of the products' outer shell, is one of the most important tests for safety of medical electrical products.

CTI Foresight Testing laboratory provides GB 8624 "Classification for burning behavior of building materials and products", divided into flat building materials and products, flooring materials, tubular insulation materials; Building products- curtain and drapes fabric, decorative fabrics for furniture products, wire and cable sleeves, electrical equipment enclosure and accessories, Foam plastics for electrical appliances and furniture products, etc. Turnaround time: 7-10 working days.

The physical and mechanical properties of plastics are closely related to temperature. When the temperature changes, the stress behavior of plastics changes, showing different physical states, showing the characteristics of phased mechanical properties. The physical state and mechanical properties of plastics when heated are of great significance to the molding process of plastics. 

Comprehensive coverage of plastic films, packaging bags, woven bags and other plastic products, around nearly a hundred subdivision testing items, according to domestic and foreign testing standards, provide authoritative testing reports.

Generally sandwich structure is used for wings, tail, fuselage, speed brake, engine compartment, etc. Compared with thin-walled skins, sandwich panels have a much larger thickness, strong resistance to instability, smooth surface, and good aerodynamic appearance. However, due to the complex manufacturing process and the difficult inspection of process quality, the application is greatly restricted. The materials of the sandwich structure sheet mainly include aluminum alloy, stainless steel, titanium alloy and various composite materials. Interlayer materials include light wood, foam plastic, etc., and metal or composite materials can also be used to make corrugated interlayer or honeycomb interlayer. The interlayer and the surface board are generally glued together, or they can be welded to form a whole.

Testing provides professional rubber track, artificial grass testing and certification services, providing officially recognized testing reports, according to national standards, industry standards, and local standards to provide comprehensive and professional physical performance testing services for plastic runways.

The thermal performance test of plastics is a part of the plastic testing, through which the thermal performance parameters of plastics can be determined, so that different plastics can be used where they are needed.As a listed testing institution, CTI can use a series of advanced equipment to test the thermal performance of plastics in accordance with ISO, ASTM, DIN, GB and other standards, and issue authoritative certification reports.

In recent years, the ubiquitous plastic products polluting the environmental is more and more serious, Europe, USA and China have launched the "Plastic limit order": The production and sale of some plastic products will be banned, green plastic products will be promoted, new form of industry will be explored, and recycling and disposal of plastic waste will be standardized, with special treatment for plastic waste. CTI can provide you with professional biodegradability testing service. Our test capacity covers disposable tableware, packing for express service, hotel supplies, resin and starch, plant fiber molding products to help enterprises control the quality and safety of materials.
