La MisoletBakeliteHistorical notes
Bakelite: it refers to everyday items that originate from PHENOLIC resins formed from a condensation reaction of phenol with formaldehyde. Firstly used in 1907, when phenolic resins were mixed with kaolin or wood flour to create products with excellent mechanical features, thermal and electrical insulation properties such as pot handles. Later, the use of resins has expanded to the manufacturing of large sheets whose inert support is made of kraft paper “bakelized paper” or cotton fabric “bakelized cloth”.
They were historically referred to as Dellite and Celeron. Dellite refers to today’s bakelized paper products, Celeron to bakelized cloth ones.
The main features of these new products are good electric and thermal insulation, easy workability and excellent mechanical properties. Products requirements are collected and codified by international standards guaranteeing their specifications, which vary according to the resin’s quality and the support used.
Bakelized Paper and Cloth are Class-E insulating materials (120°C)
They burn slowly in case of fire and are class-HB self-extinguishing products according to UL-94 standard.
MaterialsTR / N Bakelized Paper
Depending on their type, panels up to 2mm thickness can be cold-sheared or heat-sheared to obtain semi-finished products for the electric and electronic industry, such as electric insulators.
While maintaining their dielectric function, thicker panels are employed as brackets in electrical cabinets, spacers, separators and covers.
This material can also be used as operating machines working surface: its main features are mechanical strength, flatness and dimensional stability. Bakelized paper is also available in tubes.

MaterialsAT Bakelized paper
(high tension)
Laminate produced to meet the technical requirements of Italian Railways, Navy and Air Force, and for electrical transformers, given its inalterability in hot oil.
It has a higher dielectric strength than traditional bakelized paper, i.e. the maximum voltage that can be applied to a given material without causing it to break down.

MaterialsBakelized cloth
Bakelized cloth is divided into three types with different features and mechanical strength according to its threads density:
The “F” type (44 threads per cm2) is characterized by its mechanical strength and good dielectric properties;
The “FF” type (6o threads per cm2), thanks to its composition, is the most suitable to shear and process even the smallest and more complex parts;
The “G type” (24 threads per cm2) is a special product made to order, made of a sackcloth to boost its mechanical and self-lubricating characteristics.
La Misolet also provides graphite-filled Bakelized Cloth, which has excellent auto-lubricating qualities and excellent low friction workability characteristics.
Bakelized cloth mechanical characteristics are significantly more than bakelized paper ones, even though, from a dielectric point of view, they are less performing.
Bakelized cloth can be easily sheared at room temperature up to a thickness of 2mm; on the contrary, greater thicknesses need to be pre-heated.
Low-thickness bakelized cloth is used to produce washers for small electrical engines, shim washers for crankshaft, highly stressed flexural insulation vanes such as horns for vehicles. Larger-thickness cloth is used to produce vanes for vacuum centrifugal pumps, gaskets for metal pipes, shaft seals for hydraulic systems’ pistons, clutch discs, bushings, sliding guides, rolling mills layers; it is mostly used in robust, auto-lubricating and silent gears.
Bakelized cloth can also be used to manufacture tubes and rounds; the latter can be either turned from plates or wrapped.

MaterialiCanevasite V0
Canevasite F18 V0 HF is a high-pressure laminate used for mechanical and electric applications; it is produced in compliance with DIN EN 60893 as well as being V0 rating according to UL-94 standard.
This material is known for its abrasion and wear resistance, good flexibility, very low level of water absorption and temperature class up 150°C.
Machined parts crafted from Canevasite extend the life of mechanically stressed machines and components, resulting in cost saving.
This material meets the Trenitalia 374968 technical specification (cotton fabric/epoxy resin).
