Core materials for lightweight construction: How Kerdyn Green protects the environment

As a boat builder or oper­a­tions man­ag­er, you know how impor­tant it is to con­sid­er qual­i­ty and sus­tain­abil­i­ty when select­ing mate­ri­als. Using sus­tain­able mate­ri­als can not only reduce envi­ron­men­tal impact, but also bring long-term sav­ings. One promis­ing inno­va­tion in core mate­ri­als is Ker­dyn Green. It is a sus­tain­able core mate­r­i­al made from recy­cled PET foam. In this arti­cle you will learn more about Ker­dyn Green and its ben­e­fits for boat building.

What is Kerdyn Green?

Gurit’s sus­tain­able PET foam is an inno­v­a­tive core mate­r­i­al made from recy­cled PET foam. It is a sus­tain­able alter­na­tive to con­ven­tion­al core mate­ri­als while pro­vid­ing excel­lent per­for­mance and strength. The foam core is light­weight, strong and has excel­lent sound and ther­mal insu­la­tion. It is ide­al for use in var­i­ous boat­build­ing appli­ca­tions such as sand­wich pan­els, ceil­ings, floors and walls.

How sustainable is Kerdyn Green?

Ker­dyn Green is a sus­tain­able choice because it is made from recy­cled PET foam. PET foam is a by-prod­uct of the pro­duc­tion of PET bot­tles and oth­er PET prod­ucts. By recy­cling PET foam, the amount of waste is reduced and the mate­r­i­al is reused. The prod­uct is also 100% recy­clable and can be recy­cled again at the end of its life cycle.

What are the advantages of Kerdyn Green for boatbuilding?

Sus­tain­able PET foam offers many ben­e­fits for boat­build­ing, including:

  • Sus­tain­abil­i­ty: the prod­uct is a sus­tain­able choice and helps to reduce the envi­ron­men­tal impact.
  • Weight: the rigid foam board is lighter than tra­di­tion­al core mate­ri­als, which can reduce weight and improve fuel efficiency.
  • Sta­bil­i­ty: the prod­uct is sta­ble and has high strength, which can lead to a longer life of the boat.
  • Sound and heat insu­la­tion: it has excel­lent sound and heat insu­la­tion prop­er­ties, which can improve the com­fort on board.
  • Easy pro­cess­ing: Ker­dyn Green can be cut and shaped eas­i­ly and is easy to process.

In sum­ma­ry, Ker­dyn Green is an inno­v­a­tive and sus­tain­able alter­na­tive to con­ven­tion­al core mate­ri­als. Made from renew­able raw mate­ri­als, the mate­r­i­al not only offers high strength and stiff­ness, but also a low­er envi­ron­men­tal impact dur­ing pro­duc­tion and dis­pos­al. Using Ker­dyn Green in boat­build­ing, indus­tri­al and craft appli­ca­tions can help reduce envi­ron­men­tal impact while deliv­er­ing high-qual­i­ty results.

Thanks to its avail­abil­i­ty in var­i­ous sizes and thick­ness­es, as well as its com­pat­i­bil­i­ty with dif­fer­ent resin sys­tems and pro­cess­ing tech­nolo­gies, Ker­dyn Green offers a ver­sa­tile solu­tion for a wide range of appli­ca­tions. If you are inter­est­ed in using Ker­dyn Green in your next project, you can order it direct­ly from CTM’s online store and ben­e­fit from our com­pre­hen­sive sup­port and fast deliv­ery times.

Most frequently asked questions about Kerdyn Green

Com­pared to oth­er core mate­ri­als, rigid foam board offers improved sus­tain­abil­i­ty and envi­ron­men­tal com­pat­i­bil­i­ty. It is made from renew­able raw mate­ri­als and is 100% recy­clable. It also offers excel­lent mechan­i­cal prop­er­ties and can be used in var­i­ous appli­ca­tions such as sand­wich pan­els and cladding.

The prod­uct is made by com­bin­ing poly­ol and iso­cyanate, which then expand to form a polyurethane foam. The final prod­uct is then poured into molds and cut to obtain the desired shape.

Yes, the core mate­r­i­al can be used in var­i­ous appli­ca­tions, includ­ing sand­wich pan­els, cladding, hull and deck struc­tures, and inte­ri­or fin­ish­ing. It offers excel­lent mechan­i­cal prop­er­ties and is par­tic­u­lar­ly suit­able for appli­ca­tions where low weight and high stiff­ness are required.

Yes, Ker­dyn Green is easy to machine and can be cut and shaped with a vari­ety of tools includ­ing saws, drills and routers. It is also easy to glue and can be fixed with a vari­ety of adhesives.

Ker­dyn is a more cost-effec­tive option com­pared to some con­ven­tion­al core mate­ri­als on the mar­ket. Although it is made from sus­tain­able raw mate­ri­als and meets high­er man­u­fac­tur­ing require­ments, it is an eco­nom­i­cal choice for those who val­ue sus­tain­abil­i­ty and envi­ron­men­tal impact while achiev­ing high-qual­i­ty results.

You can order Ker­dyn Green direct­ly in the online store of CTM GmbH and thus be sure to receive a high-qual­i­ty and cer­ti­fied product.
