Polyamide (nylon) resins belong to a group of high-performance plastics often referred to as engineering thermoplastics. These materials are noted for their outstanding properties, including high tensile strength, excellent abrasion, chemical and heat resistance and low coefficient of friction. To know about the various nylon grades, application sectors, global growth, etc, read Global scenario of polyamide looks quite challenging

China has grown from a modest plastics consumption level of about 1 million ton in 1979, to 38 million tons in 2005. Consumption has achieved 15% average growth in the period of 1979 to 2005, possibly surpassing consumption levels of Europe and North American countries. To know about the polymer consumption in China and the projected growth, read China leads in growth of polymers & plastic products

Manufacture of colour masterbatches faces difficulties due to problems in dispersion of colourants. Organic colourants are particularly difficult to disperse in the polymer matrix in non-polar polymers such as PE and PP. Twin screw compounding, commonly used in manufacture of masterbatches, eliminates dispersion problems. To know more about the process and advantages, read Twin screw compounding improves dispersion of color masterbatches

Condensation polymers like PET, polyamide and polycarbonate tend to degrade during processing, caused by a loss of molecular weight. This leads to loss of important material properties, especially melt strength and processability, resulting in recycled and reclaimed material. Though several technologies exist to reclaim degraded polymers; there is a need for a simple, efficient and low-cost technology that can reduce the loss of molecular weight and physical properties in reclaimed condensation polymers, read in A chain extender that can restore reclaimed condensation polymers

Multi shot molding is a process in which different material shots are used to produce the final product. Multi shot molding is also called in-mold assembly, because the resulting part consists of two or more pieces made of different materials that would normally be joined in a downstream assembly operation. Industry has been slow to embrace multi shot molding, but appears to be gradually gearing up to this complex, costly, but highly capable process. To know about the applications, methods, cost effectiveness, etc, read Multi shot molding improves product quality
