Benefits of technology
This patented technology allows for better performance characteristics than existing materials like metal or rubber tubular goods used on roads by creating stronger polymeric structures that can be easily molded into different shapes without losing their strength over time. It also reduces particle formation during manufacturing processes while maintaining its properties. Overall, this innovation makes it easier and more cost-effective to produce these items at once.
Problems solved by technology
This patented technical problem addressed by this patents relates to improving the quality (strength) and durability of polymer materials like poly ethyleneglycol (PEG), while maintaining their thermal stability under harsh conditions such as those found at temperatures above 100°C without losing strength over longer periods of use. Previous methods have resulted in reduced tensile elongation values that were negatively impact upon certain applications where these types of materials had been previously applied.

Abstract
The invention provides a delayed cross-linked type silicane cross-linked polyethylene plastic. The plastic is characterized in that a specific modification auxiliary agent is used for improving the influence extent of the plastic composition by the water-contained environment, improving the storage stability of the plastic and slowing down the pre-cross-link. The use of the modifying agent aims at generating a layer of hydrophobic groups on the material surface so as to delay the contact of polymers and water molecules and delay the cross-link.
