This information should be used as an 'on the spot' reference only. If you have a phenolic resin or thermoset molding material project, chances are, the Plenco team can make it work. It is recommended for both solvent-based and hot melt formulations. There are many benefits of this, though they vary distinctly based on the underlying properties of the resin used to construct FRP. This thermoplastic resin is designed to tackify hot melt and pressure sensitive adhesives providing improved tack, peel and flexibility for EVA, SIS and acrylic based systems. Maleic Resins Vilosyn Ref No. Phenolic resin are either water soluble or alcohol soluble.

Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) CYCOM® 6070 is a 280 to 320°F (138 to 160°C) curing phenolic resin. Melting point °C 75-95 95 . Occasionally, weak or Lewis acids, such as zinc acetate, are used for specialty resins. Applications vary from commodity construction materials to high technology applications in electronics and aerospace. phenolic resin Abstract: Phenolic resin has long been used as matrix for composites mainly because of its flame retardant behavior and high char yield after pyrolysis, which results in a self supporting structure. Phenolic resins are prepared using acidic or basic catalysts. It is weather and boil proof (WBP) because phenolic resins have no melting point but only a decomposing point in the temperature zone of 220 °C. The data is provided “as is” and without any representation or warranty of any kind, including that it is fit for any purpose or of … melting point (°C) boiling point (°C) C6H5OH 40 - 43 182 C6H5CH3 -95.0 111 3. Dertophene T 115 is a light-colored terpene phenolic resin compatible with numerous elastomers. Phenolic resins are also used for making exterior plywood commonly known as weather and boil proof (WBP) plywood because phenolic resins have no melting point but only a decomposing point in the temperature zone of 220 °C (428 °F) and above. When the desired melting point is achieved, the resin is discharged into deep pans to cool, or in accordance with the present invention, melamine may be added and agitation continued 15-60 minutes before the resin is discharged. That means that the intermolecular attractions due to van der Waals dispersion forces are going to be very similar. Subsequently, carbon fabric (CF, PAN-based epoxy resin-sized T300, 3K, thickness of 0.1 mm) purchased from Xiangsheng CF Technology (Jiangsu) Co., Ltd., China, was impregnated with the mixture depending on the volume ratio of carbon fabrics to phenolic resin as 1:1. DSC samples are the blend of MPF/ PEO. Crosslinking resin for epoxy and polyester resins. TP 2040LO: A aterpene phenolic resin with reduced odor characteristics. 1 respectively for the PP, LDPE, EVA-18, PA6, PMMA, epoxy resin and phenolic resin. The photographs for melting behaviors of the polymers at the early stage of burning in the cone calorimeter are shown in Fig. Users should always follow the material suppliers processing data sheets. Unlike thermoplastics, a thermoset resin does not have a defined melting point after its initial heat treatment phase. It enhances certain properties of hot-melt and solvent-based adhesives, including specific adhesion, cold adhesion, flexibility and hot tack. Low phenol content, advantageous softening point, melt viscosity. This observation is similar to the earlier reports [7] and it was mentioned that the melting point of PBLA was found to above 250 °C. The invention provides a process for preparing phenolic curing agents which have a weight per phenolic of 240 to 280 and, when combined with imidazole cure accelerators, exhibit reduced tendency to sinter during storage by staged advancing of a liquid linear epoxy resin having an average of 2 epoxy groups per molecule and an epoxy equivalent weight (EEW) of less than 500 with a dihydric phenol. Rs 160/ Kilogram Get Latest Price. It is available on fiberglass, graphite or aramid woven broadgoods. 1.0 98-102 GP CL-7003 Powder coatings, electronic materials. This means that shapes cannot be reformed once they have cooled. This product is thermoplastic phenolic resin dried from phenol and formaldehyde. Mainly used in producing brake pad, brake shoe in the train, brake lining etc . Such a resin will generally have a set time of 20-25 seconds, a tripod flow at 80° F. of 55-85 seconds, and a 60% solution viscosity flow at 25° C. of 250-1100 cst. Strong points: high thermal decomposition, good fluidity, low content of free phenol. The inherently heat resistant phenolic resin carbonizes and chars at extreme service temperatures, it does not melt and smear like other polymer matrices. The broad peaks between 200 and 300 °C might be due to the melting point of PBLA. We've been doing it for over 80 years. Sign In. Phenolic resins are considered to be one of the big families of oligomers and polymers. Appearance: White Fake: Package: 25kg Bag: Melting Point: 98-105℃ Gel Time: 80-100 S @150℃ Flow: 50-70 Mm @ 125℃ High Light: phenolic resin, hard plastic resin s) ASTM D4402 0.68 S4 0.97 S4P3 1.17 Table 2. Fillers should be added into the PF glue. Phenolic resins are a family of polymers and oligomers composed of a wide range of structures based on the various reaction products of phenols with formaldehyde. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks.It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Physical properties of phenolic resin (PF). Phenolic resins were originally developed in the early twentieth century. In Toluene (FCB4) Seconds: Tolerance of 50 % Toluene : Colour of 50% Toluene on Gardner Scale: Suggested Uses: Disvipol-251 (Novolac) 90-100 In an inert atmosphere at high temperatures (600° - 2,000°F, 300 - 1,000°C), phenolic resin will convert to a structural carbon known as vitreous carbon. Phenolic resins are prepared with strong acid or alkaline catalysts. Come and benefit from the Plenco difference. IndiaMART > Natural and Synthetic Resins > Resin > Phenolic Resins.

Phenolic resin is used as a binder in loudspeaker driver suspension components which are made of cloth. Melting range 160 - 210°C; Field of application: Wash primer ... A stoved film of phenolic resin without PVB is brittle and has poor leveling, but by adding 5-25% of PVB to the phenolic resin solid, the coating film will perform good flexibility, good leveling, free from pinholes, and good alkali resistance. 0.2 max Approx. Maleic and Phenolic Resins We summarise below the most popular resins used for maleic and phenolic coatings. It can be processed by vacuum bag, press or autoclave methods. The reason for the higher values for phenol is in part due to permanent dipole-dipole attractions due to the electronegativity of the oxygen - but is mainly due to hydrogen bonding.
