HC Plastics News:
Modern tennis players tend to play the spin ball, so they hit the ball with the top of the racket instead of the center. The disadvantage of rotating the ball is that the player needs to swing the racket with a greater arm strength, thereby inspiring the force to spin the tennis ball. This puts an extra burden on the player's arm and can cause an arm injury. The Dunlop R&D team observed this trend and adopted a new and innovative approach to solving this problem by using BASF's Infinergy® to make the Sonic Core.
Dunlop and BASF launch high-performance tennis rackets using E-TPU materials
Sonic Core uses the industry's unique intuitive design and technical principles to provide tennis players with powerful cushioning, high rebound, speed and lightweight performance.
Infinergy® is the world's first E-TPU material to set the standard for cushioning, rebound and performance. Located in the two and ten points of the racket, the Sonic Core is built with Infinergy® Sonic Core for high performance and comfort. Dunlop's material tests showed a 46% increase in rebound height and a 2% increase in racket speed compared to Dunlop's original SonicCore material. Infinergy® materials offer impressive damping characteristics compared to standard carbon fiber racquets in addition to superior resilience, reducing vibration by 37%.
Dunlop's next-generation CX racket series will use Sonic Core technology. The new line of tennis racquets combined with Infinergy® materials offers unique technological innovations and advantages. This revolutionary material is also used in Dunlop's padelbats racket Power Flex technology.
According to Kiyoshi I kawa, director of product planning and promotion at Sumitomo Rubber Group, the Dunlop brand said: “The CX series is our flagship product launched in 2019. It is designed for the needs of players. We are committed to providing the highest quality products, and the CX series uses the latest technology. Suitable for players of all ages and levels, providing them with more powerful power, control and rotation performance, and a more comfortable experience to help players develop their abilities and inspire their love and passion for tennis. ""
Jens Dierssen, Head of Global Business Management at BASF Infinergy, said: “Infinergy® is not only suitable for footwear design, but also for the design of sports equipment such as Dunlop tennis rackets, which can enhance the player's advantage on the court. Designed in collaboration with Dunlop With the new CX racket, our goal is to achieve maximum durability, cushioning and speed in performance, setting a new benchmark for the industry."
The CX series is recognized by the Dunlop brand of tour players, including several Grand Slam finalists Kevin Anderson, who will use the new racket in the 2019 season.

Residential Sectional Garage Door
A typical version of an overhead garage door used in the past would have been built as a one-piece panel.The panel was mounted on each side with unequal parallelogram style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers. The door is balanced by either a torsion spring system or a pair of extension springs.A remote controlled motorized mechanism for opening garage doors adds convenience, safety, and security
• Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductivematerial.
• Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
• Steel doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).
• Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.
