		EPOXY 101 > WRONG QUESTION TO ASK........... IS YOUR BOARD EPOXY? AND WHY ARE XTR EPOXY BOARDS THE CHOICE OF SURFING CHAMPIONS? CARBON-KEVLAR RAILS DUAL DENSITY PARABOLIC RAILS CONSTRUCTION Many people involved in the surfboard industry at what point in the mid 80's accepted the wrong question...Is your board epoxy?? Is like asking is your car a "Yokohama" or "Good Year", based on the tires, Epoxy is just the resin (liquid) to laminate the surfboard. You can use epoxy resin to laminate any material PU (Clark foam Type), you also use Epoxy to make molded boards (pop out boards), and you have to use epoxy resin to laminate EPS (beaded foam type) and XPS (extruded , XTR Brand). The most common resin Polyester resin can't be used on EPS or XTR, the foam will melt, only in PU (polyurethane foam) you can use polyester resin. If you answer the question yes is epoxy, you must also answer is a molded or XTR or EPS or PU....very confusing. We should ask What Foam is your board made of ? (PU, EPS or XTR), or what construction is your board.(Molded, EPS/epoxy, XTR/epoxy, PU/epoxy, PU/Poly). It can get more confusing if you add any of the foams with Parabolic stringers, or Carbon rails with no stringers, or hollow boards. Just don't let anybody fool you with the wrong answers based on the wrong questions to start. Epoxy resin Is a two part liquid.......... Epoxy is a type of resin (liquid chemical) it is not foam or fiberglass. It requires two chemicals Part A (resin) and Part (B) hardener, mixed together in exact ratios to become hard and gain a particular strength. This resin is used in many industrial applications, from building for aerospace parts, electronics, sail boats, to surfboards. Most of the epoxy resins are less polluting and more environmentally friendly than others like Polyester resins, they have very low VOC's (Volatile Organic Compounds), so less material will evaporate and pollute the air. Epoxy is the material of choice where strength, water impermeability and specific flex patterns are required. There are hundreds or thousands of epoxy resin styles and applications, each with its own unique properties. Epoxy Pro has developed it's own custom epoxy resin formulation called XTR-16. This resin is ideal for extreme surfing conditions. It has perfectly balanced optimal characteristics of clarity (lack of discoloration), light weight, strength, and flexibility. See XTR comparison with similar surfboards. [Back to Top] > WHY ARE SOME SURFBOARDS CALLED EPOXY? Even though epoxy is just a resin some surfboards today called epoxy use a polystyrene foam (lightweight foam) that is commonly covered (glassed) with epoxy resin and fiberglass. If polystyrene foam is glassed with standard polyester resins, the resin will melt the foam and destroy it. This is the reason they are called epoxy surfboards, but remember Epoxy is just the resin. [Back to Top] > HOW MANY TYPES OF EPOXY SURFBOARD CONSTRUCTION ARE THERE? Basically there are two common types 1. Custom (hand shaped or computer shaped)Hand shaping an XTR Blank A piece of polystyrene foam is hand shaped to specific dimensions to meet a particular surfing specifications It can be hand shaped or machine shaped (computer / cnc) and then hand laminated with epoxy resin and standard fiberglass. The rest of the process is the same as the standard surfboard, sanded and polished if needed. The main difference is the foam and the resin, the fiberglass is the same as the standard polyester surfboard. 2. Molded (Pop Out) A piece of expanded polystyrene foam (beaded foam) is poured into a mold and is covered with several layers of fiberglass, epoxy resin, high density foam, to cover the expanded foam, some have stringers to reinforce the structure. A variation is with PVC plastic applied with heat. Then they are painted like a car and applied coats of resin and lacquers for polishing finish. These surfboards are strong, but also very stiff, with little or no flex. They don't ding easily, but when they are dinged, the surfer must get out of the water to avoid a substantial gain in board weight because the foam used is the open cell (expanded) Polystyrene, which takes on water. These boards are mass produced and offer limited choice of shape, size or color.. This systems are labor intensive and are manufactured mainly in Thailand, and China due to regulations and inexpensive labor. Molded or "Pop out" boards use expanded Polystyrene [Back to Top] > WHAT IS THE DIFFERENCE BETWEEN EXPANDED AND EXTRUDED POLYSTYRENE FOAMS? EPS FOAM EXPANDED (beaded foam) commonly known as Styrofoam:Expanded Polystyrene open cell foam - used in molded boards Used for molded surfboards and a few hand shaped surfboards. Expanded polystyrene is inexpensive and light weight (1 to 2 lb.per cubic foot). It is made mainly for insulation applications in the construction industry, because the cost is low compared to other foams. The characteristics of this foam are like the ones you see in beer coolers and Christmas tree ornaments. It has many small spheres of foam bonded together (the reason it is also called beaded foam). The structure is based on an open cell that allows water to penetrate and travel inside the foam. This foam comes in different cell sizes with different water absorption properties. The disadvantages are the water aspiration, poor flex patterns, and low resistance to compression. Because it breaks easily, it requires excessive fiberglass reinforcement. The appearance of spheres in some (beaded) foam is noticeable. The small visible balls also make the board difficult to fine shape and airbrush. *Styrofoam is a trademark of DOW Chemical. EXTRUDED FOAM (XTR) XTR closed cell extruded Polystyrene foam XTR FOAM XTR foam is a closed cell foam extruded at high speeds using expensive machinery. The main advantages are strength and imperviousness to suck water . It is very resistant to impact and compression. One of the most significant and most misunderstood qualities of the close cell construction is that almost no water absorption occurs in open dings (less than 1%). This means that a surfboard with a ding will not gain weight or change color resulting in longer memory (resilience) of the materials. Also, the flex patterns of extruded foam when glassed properly can result in enormous advantage for a positive responsive surfboard. It generates more speed that any other construction. The reason closed cell foam has not been popular with surfboard builders is the delaminations or bubbles that occurred mainly right under the front foot before ThermoVent was introduced by Epoxy Pro in 2001.. Epoxy Pro has a patent pending system called THERMOVENTING that solves the delamination problem 100%. XTR foam can be hand shaped or CNC machine shaped for production. XTR extruded foam has a nice presentation. The foam has high whiteness and can be airbrushed for a custom surfboard. [Back to Top] Note: Epoxy Pro only uses only EXTRUDED closed cell foam. XTR is a trademark of Epoxy Pro.
