Laboratory scale SSP equipment

Laboratory scale SSP equipment explained The product obtained by our polycondensation autoclave can be further polymerized in our laboratory scale SSP equipment. This solid state polymerization (SSP) increases the chain length of several grams of material (typically 10 grams). The small scale is ideal to test multiple molecular weights of a material made in a single polymerization batch. The […]

Vacuum resin drying

Vacuum resin drying explained Resins, especially polyesters, need to be dried prior to processing to maintain sufficient chain length and viscosity. At Senbis we are able to dry resins for you in quantities ranging from several grams to approximately 120 kg under elevated temperatures and reduced pressure. This way the water content in resins can […]

Solid state polymerization (SSP) rotary evaporator

Solid state polymerization rotary evaporator explained Next to drying we can offer solid state polymerization (SSP) on a kg scale. SSP is a process in which the polymer chain lengths are increased by heat in the absence of oxygen and water, in this case by means of vacuum. Increase in molecular weight means that the […]

Pilot tumble dryers (120kg and 60kg)

In the pilot plant two tumble dryers are available for the drying and SSP of thermoplastic polymers. The capacities are 60kg and 120kg. Solid State Polymerization (SSP) is a process in which the polymer chain lengths are increased by heat in the absence of oxygen and water, in this case by means of vacuum.

Polymerization (autoclave)

Polymerization (autoclave)

We have a polycondensation autoclave available for trials up to 1kg. Currently we are investigating the options for a bigger pilot plant facility with a capacity of 100kg per batch. Kindly contact us for any polymerization trials you want to do. Even if our facilites do not fit your requirements we can help you get acces […]

Refractive index

Refractive index explained The refractive index of fluids can be measured on our digital refractometer. This method is simple, effective and extensively used in order to determine the fraction of water, glycol or methanol in the distillate during condensation polymerizations.  We can also be of service for individual refractive index measurements.  

Polycondensation autoclave (1kg)

Polymerization (autoclave)

Polycondensation autoclave explained Within the Senbis laboratory we have a polycondensation autoclave available with a 1 kg one-reactor glass vessel. This kind of batch-type operation allows researches to study several process parameters (e.g. foaming, discoloration and the influence of catalysts/additives on the polymerization). All process parameters are digitally stored and online graphically represented (product temperature, […]
