The difference between EVA soles, PHYLON, PU materialEVA (Ethylene-Vinyl Acetate)Composition: A copolymer foam made from ethylene and vinyl acetate. The ratio of vinyl acetate determines flexibility and softness (higher % = softer).Manufacturing: Raw EVA pellets are expanded using heat and pressure (often with chemical blowing agents) in a mold to create the foam midsole/outsole shape. It's a relatively simple molding process.Properties:Lightweight: One of its biggest advantages.Soft & Cushiony: Provides good initial shock absorption and comfort.Flexible: Easy to bend and move with the foot.Affordable: Relatively inexpensive to produce.Durability Issues: Compresses permanently over time ("packs out"), losing cushioning. Less resistant to abrasion and tearing than PU. Can feel less stable underfoot for heavy loads or high-impact activities.Typical Uses: Basic running shoes, casual sneakers, sandals, slippers, insoles, children's shoes. Where lightweight comfort is prioritized over long-term durability/stability.PHYLONComposition: PHYLON is a type of EVA foam. It's not a fundamentally different chemical; it's a processed form of EVA.Manufacturing: The key difference. Raw EVA pellets are first expanded into large blocks or sheets under heat/pressure. These pre-expanded blocks are then reheated and compressed again in a mold to form the final midsole shape. This secondary compression step is crucial.Properties (Compared to Standard EVA):Denser & More Durable: The double-baking process creates a more compact foam structure.More Resilient: Better at retaining its shape and cushioning properties over time (less prone to packing out).Lighter Weight (Often): Can achieve similar cushioning levels as EVA with less material due to the controlled expansion/compression.Better Cushioning-to-Weight Ratio: Offers good impact protection without adding excessive weight.More Consistent: The block molding process allows for greater precision in density and shape.Slightly Firmer Feel: Than basic EVA, but can be tuned.More Expensive: The extra manufacturing steps increase cost compared to basic EVA molding.Typical Uses: Performance running shoes, basketball shoes, training shoes, higher-end sneakers. Where a balance of lightweight cushioning, responsiveness, and durability is needed. (Note: PHYLON is a trademarked name by Nike, but the process is widely used by others who might call it compressed EVA or something similar).PU (Polyurethane)Composition: A polymer made by reacting diisocyanates with polyols. Can be formulated into rigid plastics, flexible foams, coatings, adhesives, etc. For soles, it's primarily used as a foam.Manufacturing: Involves mixing liquid chemical components (isocyanates & polyols) which react and expand (often with blowing agents) directly within the mold to form the foam sole. It's a chemical reaction molding process.Properties:Durable & Long-Lasting: Highly resistant to compression set (doesn't pack out easily) and abrasion.Stable & Supportive: Offers excellent stability underfoot, even under heavy loads. Good for motion control.Denser & Heavier: Significantly heavier than EVA or PHYLON.Less Flexible: Generally stiffer than EVA foams.Can Feel "Dead" or Less Responsive: Absorbs energy but doesn't necessarily return it as quickly as some tuned EVA/PHYLON.Potential for Cracking: Older formulations or exposure to extreme elements can sometimes lead to hydrolysis (moisture-related breakdown), causing crumbling/cracking. Modern PU formulations have improved significantly in this area.Often More Expensive (than basic EVA): Due to material and processing costs.Typical Uses: Work boots, hiking boots, cleats (baseball/football), orthopedic shoes, some stability running shoes, luggage wheels. Applications demanding maximum durability, support, and load-bearing capability where weight is less critical.Summary Table:FeatureEVAPHYLON (Compressed EVA)PU (Polyurethane)Core MaterialEthylene-Vinyl Acetate FoamProcessed EVA FoamPolyurethane FoamWeightLightestLight (Often lighter than EVA for same cushion)HeaviestCushioningSoft, Comfortable (initially)Good balance, resilientFirm, SupportiveDurabilityLow (Packs out)Medium-HighHighest (Resists packing out)StabilityLow-MediumMediumHighFlexibilityHighMediumLowLongevityShortestMedium-LongLongestFeelSoft, sometimes mushyResponsive, springyFirm, stable, sometimes deadCostLowestMedium-HighMedium-HighPrimary UseCasual, lightweight trainersPerformance athletic shoesWork boots, hiking, stabilityIn Essence:EVA is the basic, lightweight, soft, and affordable foam, but it lacks long-term durability.PHYLON is a superior processing method for EVA, making it more durable, resilient, and lighter-weight-per-cushion, ideal for performance shoes.PU is a fundamentally different, heavier, denser, and much more durable/supportive material, sacrificing weight and flexibility for longevity and stability.Brands often combine these materials (e.g., PHYLON midsole with a rubber outsole, or a PU heel wedge in an EVA midsole) to leverage the strengths of each.                EVA sole                phylon sole                pu sole

The raw materials largely determine the quality of the eva rubber sole . If being in their natural and excellent state, the raw materials used in the production process can ensure a smoother production process in the later phase and a higher qualification ratio of the finished products. Also, they play an important role in pricing the products. This leads to a fact that many manufacturers now do their endeavor to carefully choose cost-effective raw materials. GuangZhou BEF Shoes Material Co.,ltd has gained continuous support from its costumers. According to the material, BEF's products are divided into several categories, and rubber sole material is one of them. All the materials or parts of BEF soles for shoe making are carefully selected. The materials or parts are only sourced from suppliers who have qualification in phone accessories supply. Being non-slip is a big selling point of this product.

The most important property of the raw materials for shoe sole suppliers is stability at any given condition. R&D department selects the appropriate raw materials based on functionality which should encompass multiple areas. Their characteristics can contribute to the identified characteristics of the finished product, such as organoleptic characteristics (color and texture), product safety characteristics, and physical properties (durability). Raw materials are the lifeblood of your business and they must flow to where they are needs in the right amount. GuangZhou BEF Shoes Material Co.,ltd has its own tr soles production base, the main products are tpr outsole. According to the material, BEF's products are divided into several categories, and rubber sole material is one of them. BEF soles for shoe making goes through rigorous quality tests.
