What is the difference between NRG and PP bodyboards?
This means NRG is lighter than PP as the Polypro Core cells are larger & less dense. This is the choice of core’s if you want a more flex for cold water or a performance board that has more flex. This core is also great for kids or women as it is much easier to control. PE versus PP PE is the most common core used in bodyboards, especially in the cooler waters of UK and northern Europe. Despite being significantly heavier than PP, it has far more flex which offers more control. PP cores are preferred by warm water riders.It is the heaviest among the three common core types, providing added stability and a solid feel in the water. PP, (Polypropylene), is the ultimate core material for bodyboarding. PP cores offer a lightweight and high-performance experience.
What is the difference between PP and PE bodyboards?
PE is more flexible and heavier than PP. PP is stiffer and lighter. But beware, this does not mean that PP is always better! The mechanical properties of the foams are affected by the water temperature, cold water makes boards stiffer and hot water makes them more flexible. Polypropylene Homopolymer (PP Homopolymer) PP Homopolymer is the most commonly used grade of polypropylene and is a semi-crystalline solid made entirely from propylene monomer. It is versatile and found in applications such as packaging, textiles, healthcare, automotive, pipes, and electrical components.Polypropylene (PP) is usually considered safe for humans. It is considered the safest of all plastics; it is a robust heat-resistant plastic. Because of its high heat tolerance, it is unlikely to leach even when exposed to warm or hot water. It is approved for use with food and beverage storage.PP is a semi-crystalline material, which is harder than PE with a higher melting point. Since the PP homopolymer is very brittle when the temperature is higher than 0°C, many commercial PP materials are random copolymers with 1-4% of ethylene, or clamp copolymers with a higher ratio of ethylene content.PE is often used for flexible packaging, while PP is for rigid packaging. Medical devices: PE and PP are both sterile and biocompatible. PE is often used for disposable devices, while PP is best for reusable devices. Automotive parts: PP is strong, durable, lightweight, and resistant to chemicals and corrosion.
What is the difference between PP and PE?
The main differences with polyethylene are that polypropylene is lighter and more resistant to high temperatures, abrasive agents and chemical solvents. It is also more resistant to breakage, however, it is less flexible than polyethylene. This flexibility allows polypropylene to display a wide range of properties based on the chosen manufacturing method. While polypropylene shares similarities with polyethylene, polyurethanes typically offer more robust physical properties, especially in extreme environments.Of the two, polypropylene can withstand higher temperatures. It is more rigid and has a higher melting point than polyethylene. Also, polypropylene is used in food packaging, as it is food-safe and moisture-resistant.Polypropylene is waterproof and extremely resistant to moisture absorption. This makes it resilient against mildew, mold, bacteria, and rot. The lighter density of polypropylene allows it to be used in applications where weight is a key consideration.
