Thermoplastic and thermosetting materials can be divided according to the “behavior” they assume in relation to heat. Thermosetting materials: thanks to their processing by heat and pressure they are affected by variations that permanently change their nature. After having made the object through molding machines, if the material is heated, it carbonises and is no… Continua a leggere Differences between thermoplastic and thermosetting materials
The thermosetting are materials that are composed of polymers joined together by chemical bonds. The highly cross-linked product structure is directly responsible for the high mechanical and physical strength (ability to withstand high stresses, loads, temperatures) compared to the most common thermoplastic polymers or elastomeric materials. Strengths: – More resistant to high temperatures compared… Continua a leggere Pros and cons of thermosetting technopolymers
ABS (acrynonitrile-butadiene-styrene) Thermoplastic copolymer obtained by polymerization of acrylonitrile, styrene, butadiene. Back Pressure Pressure which is applied to the rear end of the screw and causes a slowing of its translation backwards while the molten material accumulates in the injection chamber due to the rotation of the screw itself. Cylinder Part of the injection group,… Continua a leggere Plastic materials vocabulary
Just four years after the opening of the production site in Bulgaria, the Ansa Compositi Group sums up the first big results, proud of its work and sure of a future full of great opportunities. During the first years of the crisis that has hit all the advanced economies of the world, the Ansa… Continua a leggere Ansa Borima: a successful story
With the advent and subsequent improvement in the use of thermosetting composites (high performance plastic materials), in most cases, results were definitely beneficial compared to the most commonly metal materials used so far, both in economic terms and performance. The companies that have embarked on the path of renewal, also thanks to the collaboration with… Continua a leggere Replacing metal has become convenient: the competitive advantages of thermosetting
Compression molding is a technology that is normally used for thermosetting polymers: the process consists in compressing the plastic material inside a mold of a heated stamp, the heat of the mold fluidizes the thermosetting material and makes the pressure possible and consequently the realization of the “form”. This technology allows to realize parts of… Continua a leggere Compression Molding
The main physical properties of a thermoplastic and thermosetting products are: Extreme solidity at ambient temperature Excellent electrical isolation Excellent thermal and acoustic insulation Great portability and ease of use thanks to its light weight Durability Resistent to atmospheric agents Liquid and gas impermeability Thermoplastic products are very resistant to acids Thermosetting products are very… Continua a leggere The main physical properties of plastic
Back in 1909, the belgian-american chemist Leo Baekeland made a discovery that still nowdays gave him a reputation of being one of the most influential scientist in history: he discovered the bakelite, the first thermosetting plastic material! Studying two derivatives of petroleum – phenol and formaldehyde – Baekeland invented a material that even if heated… Continua a leggere Plastic Materials. The first synthetic plastic in history
