Polyurethane Memory Pillow

1. What is memory foam pillow?


Unlike the traditional bun and bread shape, with filling materials other than the ancient buckwheat husks, or down, seven-hole cotton, nine-hole cotton and other natural, chemical fibrous substances, block-shaped memory pillows have attracted considerable attention in recent years. Many consumers who have used these pillows feel they are more effective in relieving neck fatigue than traditional pillows, and sleep experts have pointed out that they are more suitable for the physiological structure of the human body.


The memory foam pillow is not like the traditional pillow whose interior material state can be seen at a glance, making it difficult to buy and sell; what is more puzzling is that the price of the pillow with little difference in appearance can make a big difference, with the expensive ones costing three to four thousand dollars and the cheap ones costing only twenty dollars, what is the reason for this?


2. Functions and applications of memory foam pillows


Memory foam pillows are also known as space memory pillows, space pillows, zero pressure memory pillows, slow rebound memory foam pillows, and polyether polyurethane pillows, etc. It is a pillow made of a slow rebound material that does not function to increase a person's memory, but because the pillow is often used to form the inherent shape of the human head and neck.


Polyether-based polyurethane was developed in the 1960s by the NASA-affiliated company Conman Corporation as an open cell structure with temperature-sensitive pressure-reducing properties, also known as temperature-sensitive pressure-reducing material, for use in space suits. It has been gradually used in various medical and civilian products, especially pillows made of this material, which have visco-elastic properties and can be automatically deformed as the position of the head and neck changes, keeping it in a tightly integrated position with the neck at all times, especially to hold the head in place and prevent it from sliding off and causing a stiff neck.
