Melamine-phenol-formaldehyde

The term aminoplastics has been coined to cover a range of resinous polymers produced by interaction of amines or amides with aldehydes. Of the various polymers of this type that have been produced there are two of current commercial importance in the field of plastics, the urea-formaldehyde and the melamine-formaldehyde resins. There has in the past also been some commercial interest in aniline-formaldehyde resins and in systems containing thiourea but today these are of little or no importance. Melamine-phenol-formaldehyde resins have also been introduced for use in moulding powders, and benzoguanamine-based resins are used for surface coating applications. [Pg.668]

Moulding powders based on melamine-phenol-formaldehyde resins were introduced by Bakelite Ltd, in the early 1960s. Some of the principal physical properties of mouldings from these materials are given in Table 24.1. [Pg.689]

Resins prepared by Timberlake [1] consisting of benzoguanamine-modified phenol-formaldehyde or melamine-phenol-formaldehyde resins were treated with tris(4-methoxy- phenyl)phosphine oxide to prepare coatings in printed circuit boards. Isomeric mixtures of tris(2-hydroxyphenyl)-phosphine oxide compounds were also converted into resins by Brennan [2] by reacting with tris(4-methoxy-phenyl)phos-phine oxide derivatives. [Pg.120]

Resins with improved flame-retarding properties were obtained from BMI containing phosphorus cured with different kinds of agents (Tsai et al. 2009) or by blending a commercial phenolic epoxy resin containing phosphorous and melamine phenol formaldehyde novolac with various amounts of BMI (Chiang et al. 2013).

For the purposes of this chapter, aminopolymers are defined as polymers formed by the interaction of amines or amides with aldehydes. Of the various polymers of this type which have been investigated, only two are currently of appreciable commercial importance, namely urea-formaldehyde and melamine-formaldehyde polymers. In addition, melamine-phenol-formaldehyde and benzoguanamine-formaldehyde polymers find limited application. In the past there has been some commercial interest in thiourea-formaldehyde and aniline-formaldehyde polymers but these products are now of little importance. The aforementioned polymers form the contents of this chapter. [Pg.301]

Resins prepared from melamine, phenol and formaldehyde have found some use in the preparation of moulding powders. These materials have properties which are intermediate between those of melamine-formaldehyde and phenol-formaldehyde moulding powders. In particular, mouldings have better dry-heat dimensional stability than those based on straight melamine-formaldehyde and they may be produced in a much wider range of colours than phenol-formaldehyde mouldings. Typical applications of melamine-phenol-formaldehyde materials include domestic mouldings such as iron handles where a combination of heat resistance and decorative appeal is required. [Pg.315]
