The technical services team at Avient worked closely with the European material engineering team at DENSO under the lead of Mr. THE IMPACT Through a combination of its global footprint, expert technical services, and local production, Avient accepted DENSO’s challenge and responded with a new customized formulation that exceeded performance requirements, eliminated overmolding, and reduced cycle times.

In technical applications, where strength can be a critical factor, fibers should be UV-stabilized to avoid product failure. KEY BENEFITS Avient’s UV stabilizers for fibers provide the following benefits: • High active ingredient loading options available • Little or no effect on processing speeds so plant productivity can be maintained at the highest levels • Resistance to interaction with fertilizers, pesticides and bleaching agents in the manufacturing and end-use environment • Can be combined with colors and with other additives (e.g., flame retardants) into a single combination concentrate for convenience • Product guidance and technical assistance from our experts PRODUCT BULLETIN Copyright © 2022, Avient Corporation.

A technical support team at Avient GLS Thermoplastic Elastomers conducted extensive compatibility testing to confirm proper bonding and overmolding onto the rigid substrate. Avient’s team attended all molding trials to assist in establishing proper part performance and also worked closely with the OEM on global coordination of sales, engineering, and technical support.

The first step involved a meeting between our team and Smart Hero’s technical group to understand the requirements of the outdoor lighting application. Our technical service representative attended the molding trials to help optimize processing conditions, resulting in the ideal parts for the evaluation.

Occasionally, technicians from the equipment manufacturers are used to establish the ‘entitlement’ performance of a particular machine and most major manufacturers have technical service teams to help with this activity. Maximum speed output should be attainable prior to any ‘recipe’ setting trials TECHNICAL BULLETIN The diagram below shows many of the variables that are typically present during stretch blow molding and this illustrates the complexity of the whole process. It should be recognized that due to this complexity, achieving consistent blowing performance could be regarded more of an art than a science and a high degree of technical competence, rigorous maintenance, thorough operative training and constant vigilance during operation should always be exercised.
