TYRIL™ 790

The key property of TYRIL™ 790 is its high flow that results in excellent processability. TYRIL™ 790 is specifically designed for end-use applications requiring a good balance of physical properties, optical properties (gloss, clarity or opaqueness), heat resistance and practical toughness. It is suitable for thin-wall applications and multi-cavity tools.

TYRIL™ 867E(-UV)

The key property of TYRIL™ 867E is its excellent balance of physical properties, being a true general purpose resin. TTYRIL™ 867E is specifically designed to provide good processability, good chemical resistance and very good strength. This combination of features makes Tyril™ 867E suitable for applications like refrigerator trays, mixer jars and it can also be used for the extrusion of shower partitions. The UV stabilised version, TYRIL™ 867E-UV, has excellent weather resistance.

TYRIL™ 905(-UV)

The key property of TYRIL™ 905 is its superior water-clear clarity compared to the other TYRIL™ resins. Its high thermal stability (reduced yellowing) and low base colour make it a product especially suited for self-colouring. TYRIL™ 905 is designed for applications demanding chemical resistance, heat resistance and good processability. This combination of features makes it suitable for thick-wall cosmetics packaging, thin-wall fluorescent light-diffusers and freezer drawers. The UV stabilised version, TYRIL™ 905-UV, has excellent weather resistance.
