our plastic training

impact offer a range of plastic training sessions designed to pass on the knowledge of our team.  We have over 100 years of combined experience and over 6,000,000 hours of test data within our database, with courses written which allow our clients to absorb this information and expertise into their organisations.

We can deliver courses either in person, either at your premises, our premises or conference/hotels at your convenience.  We can also offer online plastic training learning, through Skype or other platforms in order to keep costs down and maximise the learning potential of your teams.

Whatever your level of knowledge, get in touch with impact now to find out more about what plastic training courses we can offer.

Available courses

This set of booklets is meant to cover a range of topics relevant to the polymer industry at an introductory level.  They reflect in part on some of the key activities in the Impact Solutions laboratories and arise out of a course we gave to new technicians just joining the polymer industry.  The focus is very much on semi-crystalline polymers and in particular polyethylene and polypropylene, although some content can be carried over to other polymers.  Although part of a course the booklets are self contained and therefore can be read in isolation.

module 1 - catalysts & polymerisation process

click to enlarge

This booklet focuses on polyethylene, the catalyst types and different processes by which commercial polymers are manufactured.  The chemistry of chromium, organo chromium, Ziegler and metallocenes catalysts is dealt with including operating conditions, polymerisation temperatures,  activators and productivity.  The key processes covered are slurry, gas phase, solution and how these systems can be coupled to form cascade plants capable of producing broader bimodal molecular weights.

Recommended supported training time: 2-3 hours

Purchase of each booklet is accompanied with the recommended one-to-one training hours, given by one of our specialists, however you will also be given the option to book additional training hours when you add to your basket.

module 2 - introduction to molecular structure

The key molecular properties are heavily effect by the underlying molecular structure.  In this booklet a description of how the long molecules in a polymer comprise of regular monomer units.  Homopolymers and copolymers are described and the different structures in polyethylene and polypropylene.  The key techniques for characterising the molecular weight , comonomer distribution with some examples for polyethylene are included.

Recommended supported training time: 2-3 hours

module 3 - introduction to crystal structure

Polyethylene and polypropylene are semi crystalline polymers and this booklet discusses how the molecules form into amorphous and crystalline regions such as lamellae and spherulites.  Determination of the degree of crystallinity from  DSC and density column is considered.  The DSC technique is described and the form of the melting and crystallization curves discussed.  Finally examples of micrographs obtained from optical, scanning  electron and transmission microscopy are given.

Recommended supported training time: 2-3 hours

module 4 - rheology

The melt behaviour, or rheology of a polymer is heavily influenced by the polymer molecules and in turn influences the processability of a polymer.  In this booklet the effect of shear rate and swell are discussed and a particularly useful  diagram links the shear rate with the different processes, rotomoulding, extrusion, injection moulding etc.  Methods for measuring melt properties are included such as MFR, Capillary rheometry and dynamic rheometry and DMA.  Finally some examples of how rheological techniques have been applied.

Recommended supported training time: 2-3 hours

module 5 - physical & mechanical properties

click to enlarge

The physical & mechanical properties booklet starts with some initial key definitions of stress and strain and then considers tensile and flexural measurements and the influence of time dependent behaviour and creep. The section on fracture covers both fast fracture (impact) and slow crack growth.  For impact the key pendulum impact tests (Izod and Charpy) are briefly discussed while more detail is given on instrumented notch impact testing and valuable information that can be obtained from  the load displacement curve.  A number of techniques are described for slow crack growth and ESCR before fatigue is briefly discussed.  Finally the effect on selected properties of density (crystallinity) and comonomer placement in bimodal polyethylenes is discussed.

Recommended supported training time: 2-3 hours

Purchase of each booklet is accompanied with the recommended one-to-one training hours, given by one of our specialists, however you will also be given the option to book additional training hours when you add to your basket.

module 6 - film testing

click to enlarge

This slim brochure covers the key mechanical measurements for film including  tensile, tear and puncture resistance.   Optical performance of film is very important and the techniques of gloss, haze and clarity transmission are covered.  Permeation is another key area for films and the most common test method is mentioned together with multilayer barrier films.  Friction is the last topic in this booklet.

Recommended supported training time: 2 hours

Purchase of each booklet is accompanied with the recommended one-to-one training hours, given by one of our specialists, however you will also be given the option to book additional training hours when you add to your basket.

module 7 - pipe testing

This module explains why polyethylene is the material used pressure pipe applications and the means for testing of such industrial pipes. It also highlights the factors which may cause a pipe failure, the correct installation of the pipes and essential pipe testing, helping to save companies money in the long run.

Recommended supported training time: 2-3 hours

Purchase of each booklet is accompanied with the recommended one-to-one training hours, given by one of our specialists, however you will also be given the option to book additional training hours when you add to your basket.

module 8 - container testing

click to enlarge

This booklet  concentrates mainly on the UN testing methods for packages designed for the transport of dangerous goods.   The 4 major tests, drop impact, stack, air leakage and hydrostatic pressure are covered in detail . The ADR/RID standard model liquids are covered together with compatibility testing methods for environmental stress cracking.  The UN marking system is described for easy reference and some examples of container failures included.

Recommended supported training time: 2 hours

module 9 - extrusion

click to enlarge

Conversion of polymer pellets and powders into final products is largely achieved through melt extrusion.  This booklet covers the key extrusion techniques for blown film, injection and blow moulding and pipe/profiles extrusion.  The components of an extruder and twin screw compounders are introduced and description of the different extruder die heads required to make the wide range of products is described.  Rotational moulding is not covered in the booklet.

Recommended supported training time: 2-3 hours
