FAQ

  • Q What industries use SMC?

    A Automotive, electrical, construction, and industrial sectors.
  • Q Can SMC be customized?

    A Yes, fiber content, resin type, and additives can be adjusted.
  • Q What is the difference between SMC and BMC?

    A SMC is sheet-based and suitable for larger parts, while BMC is bulk form for smaller components.
  • Q How to choose PVC foam core density for marine applications?

    A 60-80kg/m3: ideal for non-structural or light loaded parts like interiors.
    80-100kg/m3: the most common range for hulls and decks.
    130-200kg/m3: for high load areas such as keel line, engine mountings, and fittings.
  • Q Is PVC foam core suitable for UAV structures?

    A Yes. PVC foam is widely used for non-structure or light-loaded components like fairings or internal liners.
     
  • Q Is PVC foam core suitable for boat hull structures?

    A Yes, PVC foam core is ideal for boat hull. It has lightweight and high strength, excellent water resistance, high impact resistance.
  • Q What is the difference between PVC foam core and PET foam?

    A PVC foam core has higher strength, low water absorption while PET foam core has lower strength and cost. PVC foam core is better for boat hull, decks and bulkheads while PET foam core is more suitable for boat interiors and cost sensitive structures. 
  • Q PVC foam core vs PMI foam: which one is better?

    A PVC foam core is better for processing temperature under 120° C  while PMI foam is recommended for higher temperature between 150-220 ° C.
  • Q Foam core vs honeycomb: which is better for marine applications?

    A Stick with foam cores especially PVC foam core if you re not looking for ultra-lightweight. Foam cores have closed-cell, which are water resistance while honeycomb has high risk of water ingress.
  • Q Can PVC foam core be used in vacuum infusion or RTM?

    A PVC foam core can be used in vacuum infusion and RTM. Hand layup is also suitable.
     
  • Q What thickness of PVC foam core is commonly used in boat decks?

    A Small watercrafts: 10-15mm
    Mid-size yachts: 20-25mm
    Large yachts: 25mm and above
    This is just for reference. Density is also a key factor determining thickness. Higher density provides better strength at the same thickness
  • Q Which core material is better for UAV, PVC or PMI foam?

    A PMI foam is the optimal material for UAV critical structures like fuselage, wings and propeller blades because it has the highest strength and stiffness among all rigid foams.
  • Q Do you have certificate?

    A Yes, we have DNV certificate.
  • Q What are the characteristics of PVC foam?

    A PVC foam offers excellent mechanical balance, is water-resistant and moisture-proof, is easy to process, and has a controllable cost.
  • Q What are the characteristics of PMI foam?

    A PMI FOAM features a temperature resistance of 180°C, robust physical properties, a closed-cell structure, and a low dielectric constant.
  • Q What are the characteristics of PI foam?

    A Pi FOAM features a temperature resistance of 300°C, sound absorption, non-toxicity, and low water absorption.
  • Q What is applications of JLON core material?

    A Through collaborations with leading universities, our products have found extensive application across aerospace,wind power, rail transport, shipbuilding, construction and other sectors.
  • Q What core material JLON supply?

    A JLon composite has full rigid structural core material supply chain. We have PVC foam,Pet foam,PMI foam and PI foam. extensive application across aerospace, rail transport, shipbuilding, construction and other sectors.
  • Q Does JLON provide SMC material samples?

    A Yes. JLON offers free standard SMC samples (5-10kg per grade), customers only need to bear the international freight cost (DHL/FedEx/UPS available). Custom JLON SMC samples have a refundable fee (refunded upon formal order), freight collected, and all samples are shipped within 3 working days.
  • Q What are the delivery and payment terms for JLON SMC?

    A JLON supports all INCOTERMS 2020 terms (EXW/FOB/CIF/DAP/), with FOB and CIF as the most commonly used for international trade. Payment terms: T/T (30% deposit in advance, 70% balance before shipment), irrevocable L/C at sight; flexible terms for long-term JLON SMC cooperative customers.
