Memory PU, full name "Memory Polyurethane", is a derivative material of polyurethane produced through a special foaming process. Its core advantage lies in breaking through the "rigid support" limitation of traditional high-resilience foamed materials. Relying on its unique "pressure-adaptive" performance, it strikes a balance between "comfortable fit" and "practical protection", and has been widely used in various fields such as footwear materials, protective gear, and accessories for rehabilitation aids.

I. Core Characteristics of Memory PU: Unique Advantages from "Material Performance" to "User Experience"

All properties of Memory PU revolve around "adapting to human body shape and relieving physical pressure", which can be specifically summarized into the following three major characteristics:

1. Pressure Adaptability and Contour Memory: Precise Fit with No Suspended Sensation

This is the most prominent characteristic of Memory PU. Different from the "immediate rebound upon compression" of ordinary PU, it deforms precisely when subjected to pressure, wrapping around the corresponding contour of the pressed object (such as feet or joints) to form a "customized fit feeling". After the pressure is fully released, it can gradually return to its original shape. For example, in the application of insoles, it can naturally fit the curve of the heel, the depression of the arch, and the protrusion of the forefoot, avoiding problems such as "misalignment and suspension" in shape.

2. Pressure Distribution and Body Protection: Even Pressure Relief to Alleviate Discomfort

The microporous structure of Memory PU (composed of numerous tiny foamed honeycomb-like structures) can "spread" the generated pressure radially to the surroundings, avoiding local excessive stress. Its specific manifestations are as follows:

• When standing or walking, it can evenly distribute the gravity from body weight across the entire sole, reducing the soreness and numbness caused by concentrated pressure on the heel and forefoot. It is especially suitable for people who stand for a long time, such as teachers, shop assistants, and medical staff.
• For people with arch collapse or flat feet, it can provide "flexible support" (not a corrective function) to fill the suspended gap of the arch and relieve arch soreness.
• For the elderly who experience walking pain due to the decline of foot function, it can reduce physical discomfort through its pressure distribution function and improve the comfort of daily activities.

3. Efficient Shock Absorption and Impact Resistance: Cushioning Protection to Reduce Sports Injuries

The foamed microporous structure of Memory PU can effectively absorb external impact force, just like a layer of "paste-like flexible cushion":

• In sports scenarios (such as running, playing basketball, outdoor hiking, etc.), it can effectively buffer the continuous impact force from the ground, reduce the conductive impact on the knees, ankles, and hip joints when the feet land, and thereby reduce joint strain.
• In daily scenarios (such as brisk walking for fitness, going up and down stairs), it can reduce the vibration caused by road bumps and keep the body more stable.

II. Application Scope of Memory PU

Based on the above material characteristics, the application scenarios of Memory PU are highly focused on fields requiring "close fit, shock absorption protection, and pressure relief". Currently, there are three major application directions:

1. Footwear Material Field: Centered on Insoles, Suitable for Various Types of Shoes

Insoles are the most mature application direction of Memory PU, which can be designed into various forms according to shoe types and needs.

2. Protective Gear Field: Suitable for Multi-Part Protection, Balancing Comfort and Support

The "fit + shock absorption" performance of Memory PU makes it an ideal auxiliary material for protective gear, which can be applied to protective equipment for different parts of the body:

• Joint protective gear: Such as knee pads, elbow pads, and ankle pads. During sports or rehabilitation training, it can closely fit the joint curve, providing cushioning protection without restricting joint movement.
• Torso protective gear: Such as waist supports and shoulder supports. It can distribute sports pressure by fitting the contour of the torso.
• Pad products: Such as wheelchair cushions, crutch handle pads, ordinary seat cushions, back cushions, yoga mats, and inner pads for sports gloves.

III. Summary: Core Value and Commercial Potential of Memory PU

The core value of Memory PU lies in "focusing on user experience". It not only retains the durability of polyurethane materials but also solves the discomfort of traditional materials through the characteristics of "memory fit, pressure distribution, and efficient shock absorption".

At present, our materials fully support OEM/ODM customized production. We can adjust the density, hardness, and appearance (such as color and texture) according to the needs of different customers to adapt to different products.
