![]() ![]() PET provides very good alcohol and essential oil barrier properties, generally good chemical resistance (although acetones and ketones will attack PET) and a high degree of impact resistance and tensile strength. for bags, bottles and foil due to its strong tensile strength and tear resistance.Īs it has a low melting point, it is also easy to form, cast and recycle. Polyethylene Terephthalate (PET, PETE or polyester) Commonly used for carbonated beverages, water bottles and many food products. HDPE is mainly used as packaging material, e.g. HDPE is an acronym for High Density Polyethylene. ![]() With a production volume of 80 million tons, it is currently the most widely used plastic in the world. Tests on HDPE have shown that with the same activation power, the activated area could be increased by 20-25% with the piezobrush® PZ3 compared to the previous model. with the piezobrush® PZ3, the surface energy can be increased to 72mN/m within a very short time and the HDPE can be ideally prepared for subsequent processes. With a surface energy of 36mN/m, HDPE has a relatively low surface energy, which makes subsequent processes such as bonding, marking or printing much more difficult. A high energy surface is a surface that is very reactive and very interested in bonding with molecules. ![]() Due to this versatility, this plastic is used, for example, as packaging, chemical containers or drinking water pipes. With a surface energy of 36mN/m, HDPE has a relatively low surface energy, which makes subsequent processes such as bonding, marking or printing much more difficult. These surfaces also have a very high surface energy. The most common processing methods are blow moulding, injection moulding, extrusion and deep drawing. Its easy thermal deformation and high mechanical and chemical stability play a particularly important role. TOPAS cyclic olefin copolymer (COC) has a low surface energy: Note that TOPAS intrinsic surface energy is essentially identical to polyolefins like PE and. With a 17 % world market share, HDPE is one of the most frequently used plastics worldwide. Sanding is one easy way to do this, creating peaks and valleys on the. It is a slightly branched polyethylene, which therefore has a high density of more than 0.94 g/cm³ for a PE plastic. Another step to increase surface energy is to roughen the surface of the substrate. HDPE is the short form for High Density Polyethylene. ![]()
